This article mainly introduces "what are the reasons for learning Java". In daily operation, I believe that many people have doubts about the reasons for learning Java. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "what are the reasons for learning Java?" Next, please follow the editor to study!

1. Java's popularity and high salary

Java developers are those who get high-paying jobs in the industry. The average Java developer earns 25W per year in China.

two。 Portable and multi-functional

Java is very portable and a versatile language. By portable, I mean Java can be used on a variety of platforms. As an open source programming language, it is platform independent throughout OS. Like its famous slogan "Write Once and Run Anywhere", you can run Java bytecode on any hardware that has JVM compatibility. Example: you can write code or create Java applications in the Windows environment and run them in any other environment, such as Linux, and so on.

Here the editor has built a front-end learning and exchange QQ group: 132667127, I have sorted out the latest front-end materials and advanced development tutorials, if you want, you can join the group to learn and communicate together.

Next, Java is considered to be one of the most common languages. First of all, it has dynamic coding, and all code is organized and stored in an object-oriented format, called classes. And then it's highly secure. It can easily use different resources on the network.

3. Java is an OOPS language

The most popular programming languages, such as Java,C + +, Clipper and so on, follow the object-oriented programming paradigm.

Object-oriented programming is a programming style that is associated with the following concepts:

1. Class

two。 Object

3. Inherit

4. Encapsulation

5. Polymorphisms

Object-based applications in Java create objects and interactions between them based on declaration classes. Therefore, Java as an object-oriented programming language, the concept of Java is highly relevant.

4. Java is everywhere.

Java is everywhere, it is on the desktop, on mobile devices, everywhere! Here, I list several areas where Java is explicitly used:

Banking: dealing with transaction management

Information technology: address implementation dependencies, the domain that employs most Java developers.

Stock market: write algorithms to know which company they should invest in

Financial services: Java for server-side applications

It is not limited to one area! Google, Tencent, Alibaba and many other giants are also using it.

So, you can rest assured that Java will not be eliminated soon.

5. Java development tools

You have a lot of powerful development tools now, but how many of the four most popular Java development tools have you used?

1. Netbeans

2. IntelliJ

3. Eclipse

4. Android Studio

All of the above tools can not only help you complete the coding process, but also provide programmers with advanced debugging.

6. Java application

As I mentioned above, Java is everywhere and it has a lot of opportunities!

Develop Web applications and their popular frameworks (Spring,hibernate, etc.)

Java is used for Android APP development

Java is used to test Web applications using various automated testing tools. For example: Selenium,QTP, used to automate Web applications and use Java to perform tests.

Big data Technology: the Hadoop MapReduce framework is written in Java

Used in the scientific and research community to process large amounts of data

7. Substantial resources and community support

Java as a programming language is Omnipresent, which means it is everywhere, from mobile phones to your set-up boxes to satellites.

Therefore, once you fully master Java, there will be huge job opportunities.

8. Java EE and its Rich API

The reason API is so popular these days is that it's easy for programmers to build applications and use different technologies without actually knowing how their internal implementations work.

When it comes to Java API, it has no compatibility issues, it handles a wide range of procedures and functions.

In addition, you will be impressed that developers provide more than 4500 API.

It provides API for I / O, networking, utilities, XML parsing, database connections, and almost everything!

9. New features of Java

The release of Java 9 ~ 10 and its features is a milestone in the Java ecosystem. I have chosen some new Java9 features, which I think are worth knowing.

The first is the Jigsaw project. The main purpose of the project is to introduce the concept of modularity, support the creation of modules, and then apply them to JDK.

In addition, the REPL tool is introduced to make it easy to try different functions. In addition, you can also use Jshell scripting, which you can actually write at once, making it very simple.

As a result, these new features of Java can help you write simple code and test it.

10. Java is Easy&Open Source

At No. 10, Java is very easy and open source. It supports the concept of FLOSS, and you can write code in Java without paying a penny.

So is there any reason to simplify it? Java is:

Concurrency: very simple parallel processing of your data

Platform independent (WORA): write and run across platforms at once

Open source: there is no cost at all to create Java applications

Powerful: powerful memory management

At this point, the study of "what are the reasons for learning Java" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
