Java is an object-oriented programming language. It has the characteristics of cross-platform, object-oriented and generic programming. It is divided into three versions, namely JavaSE Standard Edition (application on personal computers), JavaEE Enterprise Edition (server-side application), and JavaME Micro Edition (application on consumer electronics).

JavaSE (Java Standard Edition): Standard Edition, targeted at applications on personal computers. This version is the core of the Java platform. It provides a very rich API to develop applications on general personal computers, including user interface interfaces AWT and Swing, network functions and internationalization, image processing capabilities, input and output support, etc. The Applet that was so popular on the Internet in the late 1990s also belongs to this version;

JavaEE (Java Enterprise Edition): Enterprise Edition, positioned as a server-side application. JavaEE is an extension of JavaSE that adds class libraries for server development. For example: JDBC allows programmers to use SQL syntax directly in Java to access data in the database; Servlet can extend the functions of the server and handle client requests through the request-response model; JSP is a method that can use Java to Technology for embedding program code in web pages;

JavaME (Java Micro Edition): Micro version, positioned in the application of consumer electronic products, JavaME is an extension of JavaSE, including Some of the core classes of J2SE also have their own extension classes. This version streamlines the core class library to meet the needs of electronic consumer products with limited resources, and provides a modular architecture to allow different types of products to add support at any time.
