With the popularization of software development technology, more and more people begin to pay attention to the development and prospect of this industry, and many young people also want to make great efforts in this industry. The software industry involves many technologies, and Java, as the most used programming language, has become a topic of concern to many people.

There are three versions of Java: J2SE, J2ME and J2EE. J2SE belongs to the basic part of JAVA and is mainly for beginners to learn. J2ME is used for embedded development of mobile phones, and J2EE is used for enterprise-level development, such as large portals and millions of projects. You can also develop desktop applications and some games.

In addition to the above, java has many functions, such as mathematical operation, displaying graphical interface, network operation, database operation, file operation and so on. Java is widely used, which is more beneficial to small and medium-sized enterprises than other computer languages.

Learning Java is for being a programmer. When you are skilled enough, you can be a project manager, a system analyst, or you can become familiar with business knowledge when writing programs, you can work in related fields, and you can be a manager. In short, as long as you learn well and have a high-paying job, a bright future is natural.

With the wide application of java and huge market demand, the demand for Java engineers is increasing day by day, and their salaries are also rising. It is precisely because of the broad prospects of Java development that more and more people participate in Java learning. Nowadays, the quality of IT schools is uneven and mixed, so we must be careful when studying.
