Introduction submitted by helloworddd to HuaweiDevelopers [link] [comments] Huawei analytic allows developer to know how their app is used by the user, which pages get more traffic, on which page customer leaves the app. Understanding user’s habits will help you to make your app better. If your app is at a certain level or you want to move your app and business forward, you need to use analytics. To date, there are many services that offer solutions for analytics. Huawei handled analytics as a priority on HMS. https://preview.redd.it/eeqebia4ka261.png?width=1024&format=png&auto=webp&s=7041495e1e123a1e1f666119b43d3b3c61fce65b Features 1. Easy to integrate and use It is very easy to integrate and use the analytics dashboard after integrating Huawei Analytics. Moreover, you can customize your tables on the dashboard as you wish and you can easily see the data, not imposed on you. 2. Reach Huawei users As you know, google services are not used in the latest Huawei devices. When you integrate Huawei Analytics, you will reach all Huawei users and all other devices users. So Huawei Analytics a connective, not a divider. 3. Power of HMS Core Analytics gets its power from HMS Core. It is very easy to reach all the documents you need for integration or usage of dashboard. When there is a technical problem you can find technical support very easily. 4. Powerful Analysis Capabilities Ionic Framework Ionic Framework is an open source UI toolkit for building performant, high-quality mobile and desktop apps using web technologies such as HTML, CSS, and JavaScript with integrations for popular frameworks like Angular and React. Think of Ionic as the front-end UI framework that handles all of the look and feel and UI interactions your app needs in order to be compelling. Unlike a responsive framework, Ionic comes with very native-styled mobile UI elements and layouts that you should get with a native SDK on Android or iOS but didn’t really exist before on the web. Since Ionic is an HTML5 framework, it needs a native wrapper like Cordova or Capacitor in order to run as a native app. Here we will use Ionic framework with Angular and Capacitor as native wrapper. Usecase
npm install -g @ionic /cli Things need to be done
npm install @ionic-native/core --save-dev9. Run the following command to copy the “ionic/dist/hms-analytics” folder from library to “node_modules/@ionic-native” folder under your Ionic project. cp node_modules/@hmscore/cordova-plugin-hms-analytics/ionic/dist/hms-analytics node_modules/@ionic-native/ -r10. Run the following command to compile the project. ionic build npx cap init [appName] [appId]appName is the name of your app, and appId is package_name in your agconnect-services.json file (example: com.example.app). 11. Run the following command to add android platform to your project. ionic capacitor add android12. Add agconnect-services.json and signing certificate jks file to the app directory in your Android project as show below. https://preview.redd.it/is3nrjmdka261.png?width=307&format=png&auto=webp&s=eb7207b58297451684750e4900d79b9743f7c59c 13. Make sure your project has a build.gradle file with a maven repository address and agconnect service dependencies. // Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { repositories { google() jcenter() maven { url 'http://developer.huawei.com/repo/' } } dependencies { classpath 'com.android.tools.build:gradle:3.6.1' classpath 'com.google.gms:google-services:4.3.3' classpath 'com.huawei.agconnect:agcp:1.4.0.300' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } apply from: "variables.gradle" allprojects { repositories { google() jcenter() maven { url 'http://developer.huawei.com/repo/' } //This line is added by cordova-plugin-hms-account plugin } } task clean(type: Delete) { delete rootProject.buildDir }14. Add the Signing certificate configuration to the build.gradle file in the app directory. signingConfigs { release { storeFile file("mykeystore.jks") // Signing certificate. storePassword "123456" // KeyStore password. keyAlias "accountkitshowcase" // Alias. keyPassword "123456" // Key password. v1SigningEnabled true v2SigningEnabled true } }15. Add plugin to the build.gradle file in the app directory. apply plugin: 'com.huawei.agconnect'16. Add analytics kit dependencies to the build.gradle file in the app directory. dependencies { implementation 'com.huawei.hms:hianalytics:5.0.5.300' }17. To update dependencies, and copy any web assets to your project. npx capacitor syncUsing Debug Mode
Run the following command to enable the debug mode: adb shell setprop debug.huawei.hms.analytics.app package_nameViewing Debugging Event Details (Real-time Update)

Each app is allocated with a unique AAID on the same device so that statistics can be collected and analyzed for different apps (for example, statistics on the number of active users). In addition, personal data from different apps is isloated to protect user data privacy and security.1234567891011 /** * Obtains the app instance ID from AppGallery Connect. */ async getaaid() { try { const aaid = await this.analytics.getAAID(); console.log('getAAID -> Success -> aaid : ' + aaid); } catch (err) { console.error('getAAID -> Error : ' + err); } } Records predefined eventSuch events have been predefined by the HMS Core Analytics SDK based on common application scenarios. It is recommended you use predefined event IDs for event collection and analysis.In our app, we will record predefined SIGNIN and SIGNOUT event. /** * Report predefined signin events. */ async onSendLoginEvent() { const event_name = HAEventType.SIGNIN; const event_value = {} const value = { "event_login": "success" }; try { const event = await this.analytics.onEvent(event_name, event_value); console.log('onSendLoginEvent -> Success'); } catch (err) { console.error('onSendLoginEvent -> Error : ' + err); } } /** * Report predefined sign out events. */ async onSendLogOutEvent() { const event_name = HAEventType.SIGNOUT; const event_value = {} const value = { "event_logout": "success" }; try { const event = await this.analytics.onEvent(event_name, event_value); console.log('onSendLogoutEvent -> Success'); } catch (err) { console.error('onSendLogoutEvent -> Error : ' + err); } } Records custom eventSuch events can be used to meet personalized analysis requirements that cannot be met by automatically collected events and predefined events.In our case, we will record user info as custom event. Note: The ID of a custom event cannot be the same as that of a predefined event. Otherwise, the custom event will be identified as a predefined event. /** * Report custom events to record user info. */ async onUserInfoEvent() { const name = 'userinfo'; const value = { "userName": this.fullname, "userEmail": this.userEmail, "userImage": this.imageUrl }; try { const event = await this.analytics.onEvent(name, value); console.log('onUserInfoEvent -> Success'); } catch (err) { console.error('onUserInfoEvent -> Error : ' + err); } } Setting User ProfilesSets user attributes. The values of user attributes remain unchanged throughout the app lifecycle and during each session.Note: A maximum of 25 user attributes are supported. If the name of an attribute set later is the same as that of an existing attribute, the value of the existing attribute is updated. async onSetUserProfile() { const userProfileName = "user_profile_name"; const userProfileValue = this.fullname; try { const setUserProfile = await this.analytics.setUserProfile(userProfileName, userProfileValue); console.log('setUserProfile -> Success'); } catch (err) { console.error('setUserProfile -> Error : ' + err); } }Analytics event on Dashboard 1.

Once you have copied the “ionic/dist/hms-analytics” folder from library to “node_modules/@ionic-native” folder under your Ionic project. Make sure to add HmsAnalytics inside providers in app.module.ts providers: [ StatusBar, HMSAnalytics, SplashScreen, { provide: RouteReuseStrategy, useClass: IonicRouteStrategy } ]2. The ID of a custom event cannot be the same as that of a predefined event. Otherwise, the custom event will be identified as a predefined event. Conclusion In this article you have learned how to integrate HMS Analytics into ionic application, record custom events and monitor them in AppGallery Connect. You can use custom events with user attributes in your apps to see user behaviours, so that you can improve your app depend on them. References Huawei analytics kit |
When it comes to programming paradigms, it's easy to associate religious piety, and every religion has certain rationality in its creeds, but it can be painful to follow only one dogma, as can programming paradigms. submitted by helloworddd to HuaweiDevelopers [link] [comments] https://preview.redd.it/3ig49fmngkz51.png?width=2708&format=png&auto=webp&s=858629d1e75d8f99a2f8d84e2f04f616b115960a Case 1 Case 1: The code abstract is from the training materials of an enterprise. The main code logic is to print the scores of each class and find the average score of students' non-F-level courses. class CourseGrade {public String title; public char grade; } public class ReportCard { public String studentName; public ArrayList public void printReport() {System.out.println("Report card for " + studentName); System.out.println("------------------------"); System.out.println("Course Title Grade"); Iterator What are the problems with the preceding code? The member variable is public, which lacks data encapsulation. The system does not check whether the client is empty. The value may be divided by 0. Note: Assume that this field is not empty. In addition, the logic may be incorrect. Why is the total score calculated for non-F courses and the divisor calculated for all courses? Ignore this question first. The variable avg is used for multiple purposes, that is, the total score and the average score. The client variable name is difficult to understand. ! (grade.grade == 'F') somewhat counterintuitive The while loop does two things, prints the grades of each lesson, and counts the scores. The training materials do not provide standard solutions. Try to optimize the code, use Java8 Stream to simplify the calculation process, and segment the code. The following functions are extracted for each type of printing: private void printHeader() {System.out.println("Report card for " + studentName); System.out.println("------------------------"); } private void printGrade() {System.out.println("Course Title Grade"); cliens.forEach(it -> System.out.println(it.title + " " + it.grade)); } private void printAverage() {double total = clients.stream().filter(it -> it.grade !='F') .mapToDouble(it -> it.grade - 64).sum(); System.out.println("------------------------"); System.out.println("Grade Point Average = " + total / cliens.size()); } public void printReport3() {printHeader(); printGrade(); printAverage(); } Note: If only the average score of non-F is calculated, you can perform the following operations in a row: Case 2: Let's look at the code. The code is very clear: · Filter out transactions of the GROCRY type. · Sort by value in descending order. · Use the ID field of each field. · Output ID list. Does this look like a SQL statement: select t.id from transactions t where t.type =='GROCERY 'order by t.value desc 1 Wrap it over Now that Java 8 is widely used, Stream and Lambda should become accustomed to it, not showmanship. There are many tutorials on the Internet. If some students are not familiar with their usage, you can find more materials to get familiar with them. Stream, as its name is, acts as a data production pipeline, gradually superimposing intermediate operations (algorithms and calculations) to transform a data source into another data set. I have learned C# and learned about Language Integrated Query (LINQ). The usage of LINQ is clearer and simpler than Java Stream and Lambda. The following is an example: var result = db.ProScheme.OrderByDescending(p => p.rpId).Where(p => p.rpId > 10).ToList();LINQ is born for data query. It can be regarded as Domain Specific Language (DSL) and is also a set of functional programming (FP) concepts. Remember the following two points: · Monad is a design pattern that decomposes an operational process into multiple interconnected steps through a function. · Lambda expression is an anonymous function, and it is named based on the lambda calculation in mathematics. FP has other features: pattern matching, currying, bias function, closure, tail recursion, etc. Students who are interested in FP feel may find materials to learn. Currently, mainstream languages introduce some FP features to improve the data expression capability of languages. C++11 introduces Lambda expressions and provides two basic libraries: Python provides functools libraries to simplify some functional programming. The following is a simple example: 2. Functional programming Of course, adding features like lambda to object-oriented languages is not functional programming, but mostly grammar candy. The programming paradigm is not the grammar of the language, but the way of thinking. Object-Oriented Programming (OOP) has been very successful over the past 20 years, while Functional Programming (FP) has evolved, each of which addresses different scenarios: · Object-oriented is an abstraction of data. For example, an object is abstracted to focus on data. · Functional programming is a process abstraction thinking, which is to abstract the current action, focusing on the action. Actual business requirements are usually reflected in business activities, which are process-oriented. That is, data sources are input first, a series of interactions are performed under certain conditions, and then results are output. What is the difference between a procedure-oriented and a functional formula? Process-oriented is to divide the action into multiple steps. Therefore, syntax such as if and while is used to support different steps. Compared with process-oriented, the functional style emphasizes the execution result rather than the execution process. It uses several simple execution units to gradually sympathize with the calculation result and deduce complex operations layer by layer instead of designing complex execution processes, therefore, purely functional programming languages do not require syntax such as if/while. Instead, they use pattern matching and recursive invoking. Object-oriented programming constructs readable code by encapsulating variable parts, while functional programming constructs readable code by minimizing variable parts. Another feature of the function is described as follows from the Java Stream implementation: The function does not maintain any status, and the context data remains unchanged. The input parameters are thrown after being processed. Based on the preceding understanding, we can first abstract world things as objects through OOP and then abstract the relationships and interactions between things as execution units through FP. This combination may be a good solution to the implementation of business activities. 3. Avoid single paradigm When it comes to programming paradigms, it's easy to associate religious piety, and every religion has certain rationality in its creed, but it can be painful to follow only one dogma. The same is true of the programming paradigm, just as Java was purely object-oriented before 1.8, you find it very cumbersome. As Erlang is purely functional, you will find that simple logic can sometimes be very complex. In recent years, the rise of data analysis, scientific computing, and parallel computing has led to the recognition that functional programming addresses the charm of data, and it has become increasingly popular. In these areas, programs are often easy to express in data expressions, and functional expressions can be implemented with little code. In actual service software, many logics are also used to process data, including the CURD, data combination, filtering, and query. Therefore, functional programming is supported in many languages, improving the ability to express data processing. Understanding the new programming paradigms and using them in due course will help you get more done with less. Whatever programming paradigm, they're tools, and in your toolbox, there might be hammers, screwdrivers, and when to use this tool depends on the problem to be solved. 4. Conclusion The case in this article is only an introduction to the concept of functional programming. Functional programming provides us with another way of thinking: how to efficiently and concisely query and transform data. Many languages support some functional capabilities, which need to be constantly learned and used in reasonable scenarios. This document is translated from https://bbs.huaweicloud.com/blogs/210037 |
interface First { fun runFirst() } interface Second { fun runSecond() } fun test() { val both = object : First, Second { override fun runFirst() { println("first") } override fun runSecond() { println("second") } } // MainKt$test$both$1 println(both.javaClass.typeName) // first // second both.runFirst() both.runSecond() }My variable both in the given example is implicitly typed. But what is the Type? IntelliJ says
interface Both: First, SecondBut then I could simply make it a non anonymous class instead of an interface.

Hello,
I have gotten so many replies and messages since my last post in this thread, that I can't answer them all individually. Previous topic:
https://www.reddit.com/TibiaMMO/comments/h8tu5u/a_great_tip_for_brazilians_venezuelans_and_othe
It has been shared on multiple subreddits so I have no idea where to even post this. But I'd like to come up with a follow-up thread with some more information. The internet is the most powerful tool that mankind has ever invented. You have the ability to reach thousands, millions and even billions of people with just a computer and some internet access.
If you're on this subreddit, chances are you're already playing Tibia and you already have a computer and internet access. It doesn't need to be the best internet, but as long as websites will load (eventually) you are good to go.
In this topic I will go more in-depth on web development and software engineering. If you have a very slow internet connection, you may want to look into web development instead of software development. An application/software is much heavier (larger file size) than a website. And most developer jobs require that you send and download files, back and forth, between you and your company's server. So if you feel like your internet is too slow to send a lot of files - do not worry! There are plenty of jobs.
First, I will go through some more details on how to learn web development and software development. After that, I will list a few other kinds of jobs that you can do remotely. These types of jobs can be done from anywhere in the world as long as you have internet access.
Part 1: Some languages you should learn
What is web development? Well, it can be a lot of things. You perhaps make websites for shops/restaurants/hair dressers/dentists, or you work for a big company and work on their web application, like Outlook, Discord or Spotify (which can all be accessed via a browser: their web app). You can also work with design and user experience, instead of programming. Being a web developer can mean so many different things, it's impossible to name them all. But most web developers are just developers: they program. They make websites, and they either sell the websites to companies (as a consultant) or you work full/part-time for a company.
I can not provide in-depth information about every single thing, but I can give you some pointers. The very basics any web developer should know is this:
HTML (HyperText Markup Language) - it's what almost all websites use as a foundation. This is not a programming language, but it is a markup language. If you want to build websites, you pretty much have to know this language. Don't worry though, it is easy. Not so much to learn. You can learn all about it in a few weeks.
CSS (Cascading Style Sheets) - it's what will add colors and shapes to your website. If you want to focus more on design (also known as front end development) then this is where you want to gain a lot of knowledge.
Python - A very simple language to learn. This language is very often the first programming language that developers start using. You can use it for a lot of things. This language is used in the back of a lot of websites. Google has been using Python for years and still is. It's great for web scraping and making web requests. If you want a language to practice your algorithms, then this language is awesome.
PHP - This used to be a very popular language, but not so much these days. However, it is very good to know how this works because it's very simple to learn and also very functional in some cases. If you want to transmit or withdraw information from a database to your website, then this (in combination with SQL) is a great way to do so. Whenever you make a login system or a contact form, the data must be sent somehow to a recipient or a database. PHP will help you do that. It is a server-side language, which means it will run in the back of the website.
SQL - To be able to communicate with databases (for example: save data, update data, or insert data) you can use different languages for that. But SQL is probably the most widely used language for this. It is basically just a bunch of commands that you tell your website or app to do. If you have a web shop for example, you will need a database to store all your product information in. You can for example use MySQL as your database and then use the SQL language to extract data from your database and publish it as a list of products on your website.
JavaScript - Perhaps the most powerful language at the moment. Anyone who is good at JavaScript will be able to learn most other modern programming languages. In recent years, the demand for good JavaScript developers has skyrocketed. It's because more applications are becoming web based, and JavaScript is probably among the most useful languages to use. You can use it for so many things. Previously JavaScript was only being run on the client side of the website (that means in the user's browser). But in recent years, there has been massive development of this language and you are now able to build servers, connect to databases and do very powerful web applications using just this language. A great tutorial for JavaScript was made by Tony Alicea: https://www.youtube.com/watch?v=Bv_5Zv5c-Ts This video is "just" 3.5 hours, but it's the intro. There is a much longer version of it, and you can download it for free if you search for it. Just find it as a torrent and watch it. It's probably the best tutorial I have seen for JavaScript.
C# - It's pronounced as "C Sharp". This language has been dominating the software engineering market for decades at this point. Everyone loves it. It's relatively easy to learn and you can build a lot of stuff in C#. It's very much like JavaScript, but focuses more on application development rather than website development. I would however try to avoid learning this language if you have very slow internet, since you will most likely be sending a ton of files back and forth. But if application (computer & phone) is your thing, then this language is great. There are so many tutorials on this, but there is 1 channel on YouTube which teaches a lot of the basics in C# (and many other languages) and that channel is called ProgrammingKnowledge. Sure, his C# videos may be old now but most of it is still relevant and useful. You will learn a lot by watching his videos. It's always good to start from the beginning and then when you're familiar with that, you can learn more about the recent updates in C#. https://www.youtube.com/watch?v=V2A8tcb_YyY&list=PLS1QulWo1RIZrmdggzEKbhnfvCMHtT-sA
Java - This is pretty much 90% identical to C# as I wrote above. Widely used, relatively easy to learn the basics and there's plenty of jobs. If you like making android apps, this language is for you.
Part 2: Technologies and useful tools
To become a web developer you will need a few tools. You need a text editor, a FTP client, a SSH client and some other things. Also a good browser.
Text editor: Visual Studio Code, Atom, Sublime Text, Brackets - There are many different text editors but at the moment, I highly recommend Visual Studio Code. It has so many built-in features it's honestly the only thing you may need.Don't forget to install Notepad++ as well - this very basic editor is so handy when you just quickly need to edit some files.
File archiving: WinRar, 7-Zip - You need some way of archiving projects and send it to your customer or employer. These are basic tools anyone should use. I personally use Winrar.
FTP (File Transfer Protocol): FileZilla - This tool will allow you to connect to your website's file manager and upload your files to it. There are many tools for connecting to an FTP server but this is the most popular one, it's simple and it works great.
VPS (Virtual Private Server): Amazon Web Services, Google Cloud - If you want to practice building web applications or want to host your own website as a fun project, it's great to use a VPS for that. Both Amazon and Google offers 365 days of free VPS usage. All you need is a credit card. However, they will not charge you, as long as you stay below the free tier limit. A VPS is basically a remote computer that you can connect to. I highly recommend that, if you have a slow internet connection. Those VPS-servers (by Amazon and Google) usually have 500mbit/s internet speed, which is faster than most countries in the world. You simply connect to them via Remote Desktop, or by SSH. Depending on what type of server you are using (Windows or Linux).
SSH (Secure Shell): Solar-PuTTY, PuTTY - If you for example have a web server where you store applications and files, a great way to connect to it is by using SSH. PuTTY is pretty much the standard when it comes to SSH clients. But I really love the version created by SolarWinds. When you download that one, do not enter your personal details. Their sales people will call you and haunt you! Haha.
File Searching: Agent Ransack - When you have many files and try to locate a specific document or file, you may want to use something like Agent Ransack. Much faster than the traditional search feature in Windows and it is much more accurate.
IDE / Code Editor: Visual Studio - Great tool to use when you want to create applications in C# for example. Do not confuse this with Visual Studio Code. These are two very different tools. This tool (Visual Studio) is more designed for Windows applications. Not just websites. I only recommend getting it if you plan to make programs for Windows.
Web host & domain: NameCheap, Epik, SiteGround - If you develop websites on your own, or maybe want to create a portfolio website, you will need a domain name and web hosting. I have personally used all of these 3 and they are very cheap. NameCheap has some of the cheapest domains and great web hosting for a low price. Their support is also great. Same with SiteGround. And if you want to buy a domain anonymously (with Bitcoin for example), then you can use Epik. Low prices and great customer service on all these 3 websites.
Web Server: XAMPP, Nginx - If you plan to practice PHP, you will need to have a web server on your local computer. If you have Windows, I would highly recommend installing XAMPP (Apache). It is very easy to use for beginners. If you're on Linux, I would recommend Nginx. Also check our PhpMyAdmin if you want to quickly setup a MySQL database locally.Bonus tip: If you use Visual Studio Code to create websites in HTML, CSS and JavaScript: then install the extension "live server" and you can run your applications on a live server without setting it up yourself. Tutorial: https://www.youtube.com/watch?v=WzE0yqwbdgU
Web Browser: Mozilla Firefox, Microsoft Edge Insider, Google Chrome - You need one of the latest web browsers to create websites these days. Since I prefer privacy over functionality, I've always loved Firefox. But recently, Microsoft has been improving its new version of Edge a lot (based on Chromium) and it's also very popular. If you want all your personal details to be saved and have good tools for web development, then use Google Chrome. Don't forget to utilize the built-in developer tools. You can access it in any of these browsers by pressing F12.
Other things you may want to look into:
Web services, SSL certificates, Search Engine Optimization, Databases, API, Algorithms, Data Structures

If you want to learn in-depth about algorithms, data structures and more. Then you can take a look at the curriculum of the top-tier universities of USA. Such as: UC Berkeley, Harvard and MIT. These courses are very hard and are specifically for people who want to become experts in software engineering. You can enroll some of them for free, like the one on Harvard. And by having a such diploma (which costs $90 extra) can get you a lot of job opportunities. You can enroll those courses if you want, but it can have a fee. But just take a look at what they are studying and try do their exercises, that is 100% free. Get the knowledge. It's mostly on video too! These course below are the very same courses that many of the engineers at Facebook, Google, Amazon, Apple, Netflix, Uber, AirBnb, Twitter, LinkedIn, Microsoft, etc. has taken. It's what majority of people in Silicon Valley studied. And it's among the best classes that you can take. These course are held by some of the world's best professors in IT.

Anonymous classes that we considered above are just a particular case of nested classes. Generally, a nested class is a class that is declared inside another class or interface: Looking at the diagram, we see that anonymous classes along with local and nonstatic member ones form the so-called inner classes. We may use java anonymous classe 3 ways. Anonymous inner class that extends a class. Anonymous inner class that implements an interface. Anonymous inner class that defined as arguments of method / constructor. 2. Anonymous class example class Greeter { public void wish() { System.out.println("Hello"); } } Java Anonymous inner class. A class that have no name is known as anonymous inner class in java. It should be used if you have to override method of class or interface. Java Anonymous inner class can be created by two ways: Class (may be abstract or concrete). Interface; Java anonymous inner class example using class Anonymous Inner Class in Java is an inner class or nested class. Inner class is a class which is present inside an outer class. So an anonymous inner class is an inner class that has no name. It is either a subclass of a class or an implementation of an interface. So if we have to override method of class or interface we can use anonymous inner class. However, you cannot declare constructors in an anonymous class. Examples of Anonymous Classes. Anonymous classes are often used in graphical user interface (GUI) applications. Consider the JavaFX example HelloWorld.java (from the section Hello World, JavaFX Style from Getting Started with JavaFX). This sample creates a frame that contains a Say 'Hello World' button. The anonymous class expression is highlighted: Prerequisites :- Nested Classes in Java. It is an inner class without a name and for which only a single object is created. An anonymous inner class can be useful when making an instance of an object with certain “extras” such as overloading methods of a class or interface, without having to actually subclass a class. An anonymous inner class is an inner class that is declared without using a class name at all – and that of course is why it’s called an anonymous class. An anonymous inner class also has some pretty unusual syntax. Let’s go through an actual example with some code of an anonymous inner class to help you understand what it is exactly: Anonymous inner class example: Anonymous Class Java Example. Posted by: Simranjit Singh in Core Java June 3rd, 2020 1 Comment Views. In this article, we will see examples of the anonymous class in Java language, which is a very important aspect of Programming. 1. Introduction. An anonymous class must be defined inside another class. Hence, it is also known as an anonymous inner class. Its syntax is: class outerClass { // defining anonymous class object1 = new Type(parameterList) { // body of the anonymous class }; } Anonymous classes usually extend subclasses or implement interfaces. Here, Type can be. a superclass that an anonymous class extends As abstraction is clear to you we will look into one example where we have used interface or abstract class to write the anonymous inner class. Example of Anonymous Class in Java. Following are the examples of anonymous class in java: Example #1. Anonymous class for defining the method of an interface. Code: interface First {void printing();}
