1. Android Applications
Many Android applications are developed by Java programmer developers. Although Android utilizes a different JVM and different encapsulation methods, the code is still written in Java. JAVA games are supported in a significant portion of cell phones, which has led to many non-programmers becoming familiar with JAVA.
2. Server Programs in the Financial Industry
Java is widely used in the financial services industry, and many third-party trading systems, banks, and financial institutions have chosen to develop in Java because of the relative security of Java. Large multinational investment banks use Java to write front- and back-office electronic trading systems, settlement and confirmation systems, data processing projects, and other projects.
3. Web sites
Java has taken its place in the field of e-commerce as well as web site development. Developers can use many different frameworks to create web projects, SpringMVC, Struts 2.0, and frameworks.
4, embedded field
Java in the embedded field has a lot of room for development. In this platform, only 130KB to be able to use Java technology (on smart cards or sensors).
5, big data technology
Hadoop and other big data processing technologies many of which use Java, such as Apache's Java-based HBase and Accumulo and ElasticSearchas well.
6, high-frequency transactions in the space
The Java platform improves this platform's features and even if compiled, he is at the same time able to pass data like C++. It is for this reason that Java has become the language of choice for programmers writing trading platforms, because although the performance is not as good as C++, developers can bypass issues such as security, portability and maintainability.
7. Scientific Applications
Java is a good 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.
Expanded:
The uses of java have been countless and endless, with unparalleled capabilities, in addition to considerable savings in time and development costs, programmers are free to use with the help of the language, the Existing hardware and software system platforms, because java is independent of any platform. Specific application areas are summarized as follows:
The first area, desktop application development;
The second area, embedded system development;
The third area, e-commerce system development;
The fourth area, enterprise-level application development;
The fifth area, interactive system development;
The sixth area
The sixth area is multimedia systems development;
The seventh area is distributed systems development;
The eighth area is Web applications development.
