What are the main application fields of java?

In the real world, Java is used in many places, from e-commerce websites to Androidapps, from scientific applications to financial products, such as electronic trading systems, from games like My World to desktop applications of Eclipse, Netbeans and IntelliJ, from open source resource libraries to J2MEapps, and so on. The following java courses take you to know more about the application fields of java.

1, Android application

If you want to know where the Java application is, you are not far from the answer. Open your Android phone or any App, which is completely written in Java programming language, using Google AndroidAPI, much like JDK. Android just started a few years ago, and today many Java programmers are developers of Android App.

2. Server applications in financial services

Java has a great application in financial services. Many global investment banks, such as GoldmanSachs, Citigroup and others, use Java to write front-end and back-end electronic trading systems, settlement, information confirmation systems, data processing projects and other projects.

Java is used to write server applications, but most of them have no front end. They all receive data from one server (upper layer), process the data and send it to other processing systems (lower layer). JavaSwing is very popular because it can develop clients with graphical user interfaces for traders to use, but now C# is rapidly replacing the Swing market, which brings pressure to Swing.

3. Website application

Java is also widely used in e-commerce and website development. You can use many RESTfull frameworks and develop with similar frameworks such as SpringMVC and Struts2.0. Even simple Servlet, JSPs and Struts are popular in various government projects. Many websites of government, medical care, insurance, education, national defense and other departments are based on java.
