Java has a wide range of applications, can be said to be the most popular now, all over the various industries, can be seen where its advantages.

1, the field of big data

Hadoop and other big data processing technologies are generally used in Java, of course, other languages are also used to Java?based?HBase and Accumulo and ElasticSearchas. But Java does not account for much space in this area, but as long as Hadoop and ElasticSearchas can grow and expand. ElasticSearchas can grow and expand, Java still has the potential to take part.

2. Android apps?

If you want to know where Java apps are, open your Android phone or any app, they are written entirely in the Java programming language with Google's Android API, which is very similar to the JDK. A few years ago Android was just starting to take off and today there are many Java programmers who are developers of Android apps. By the way, although we mentioned in our previous article about how Android Apps work that Android uses a different Java Virtual Machine and a different wrapper, the code is still written in Java.

3. Web domain

Java is likewise widely used in e-commerce and web development. You can utilize many RESTfull architectures that are developed using Spring MVC, Struts 2.0 and similar frameworks. Even simple Servlets, JSPs and Struts are popular for various government projects and many government, healthcare, insurance, education, defense and other sector websites are built on top of java.

4, software tools

Many common software and development tools are written and developed using Java. For example, Eclipse, IneteliJIdea and Netbans?IDE.? Trading Systems Third-party trading systems, which are now a large part of the financial services industry, are also written in Java.? For example, the popular trading platform Murex, which is also written in Java, connects with many bank front offices to provide services.

5. Embedded domain?

Java?There is a lot of room for growth in the embedded space. On this platform, you only need 130KB to be able to use?Java?technology (on smart cards or sensors).

Initially, Java?was designed to work on embedded book devices. In fact, this was just one of those areas where it was a "write once, swim anywhere" project, and now it looks like it is.

6. Other areas

Java is still the best choice for scientific applications, including natural language processing. The main reason is because Java is better than C++ or other languages relative to its security, portability, maintainability, and concurrency of other high-level languages.

It can be said that Java is widely used in various fields as the default development language in the software industry, and practitioners agree that Java has a bright future.

I hope this helps!
