This article mainly shows you "what applications of Java technology in life", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "what are the applications of Java technology in life" this article.

1. Android App

If you want to figure out where Java is used, you are not too far from that goal. Open your Android phone and any App, which is developed using the Java language and based on GoogleAPI (similar to JDK). Android support has improved a lot over the years, and many Java programmers have become Android App developers. Android uses different Java virtual machines and different packages, but the code is still written in Java.

2. The application of financial server.

Java plays an important role in financial services. Many banks, such as China Construction Bank and Bank of China, use Java to develop foreground and backstage electronic trading systems, provide solutions and confirmation systems, data processing projects, and so on.

Java is mostly used to develop server-side applications, rarely to develop a front-end, which receives data from a server, then processes it and sends it to other processes.

3. Java Web application

Java also has many applications in the field of e-commerce and Web applications. There are many RESTful-style services developed using Spring MVC, Structs2.0, and similar frameworks. Even building a simple Web application that relies on Servlet, JSP and Structs is very popular in a variety of government projects. Many government departments, such as the Health Bureau, the Insurance Department, the Ministry of Defense and so on, have Web applications developed by them using Java.

4. Software tools

Many useful software and development tools are developed in Java, such as Eclipse, interllij, Netbeans IDE. I think most of the desktop applications used are also developed in Java. So for a while, Swing was very popular in developing clients, especially in the financial industry and investment banks. Now, Java FX is becoming more and more popular, but it is still not a substitute for Swing, and C# has almost replaced Swing in the financial field.

5. Transaction application

Third-party trading applications are also developed in Java as part of the larger financial services industry.

Popular trading applications like Murex are also developed in Java, and many banks use them to connect the front and back ends.

6. J2ME application

Although the emergence of iOS and Android has almost wiped out the big market for Samsung phones with J2ME, there is still a big market for low-end Nokia and Samsung phones using J2ME. For a time, almost all the games and software available on Android used MIDP and CLDC, which were part of the J2ME platform. J2ME is used in some products such as Blu-ray discs, set-top boxes and so on.

One of the reasons WhatsApp is so thin and popular is that it is available on the J2ME platform for all Nokia phones.

7. Embedded field

In the embedded field, Java also has a lot of applications. It shows how powerful the platform is, and you only need 130kb to www.1000bibles.com Java technology (on smart cards or sensors). Originally, Java was designed for embedded devices. In fact, this is part of Java's original intention of "write once, run everywhere", and now it seems to be a success.

8. Big data technology

Hadoop and other big data technologies use Java in one way or another, such as Apache's reliance on Java's HBse and Accumulo (open source) and ElasticSearch. But Java does not dominate the field because there are other technologies such as MongoDB developed with C++.

If Hadoop or ElasticSearch grows, Java is likely to gain a major share in this area of development.

9. High-frequency trading areas

With the help of JIT technology, the performance of Java platform has been greatly improved, and the transmission performance has reached the level of C++. For this reason, Java is very popular in developing high-performance systems, with slightly worse performance than machine languages, but you can safely compromise-lightweight. Maintainability brings faster speed. For an inexperienced C++ programmer, it can only make applications slower and unreliable.

Take stock of the top 10 applications of Java technology in daily life!

10. Scientific application

Now, Java is often used as a default choice for scientific applications, including natural language processing. The main reason for this is that Java is more secure, lightweight, maintained, and has better advanced concurrency tools than C++ and other languages.
