In Java, an application is mainly composed of a class that contains the main method. The main method serves as the entry point of the program and is called first when the program is run. The main steps are as follows:<\/p>\n

    \n
  1. Write a Java class that includes a main method.<\/li>\n
  2. Compile Java class files to generate .class files.<\/li>\n
  3. Run a Java application by executing the compiled .class file using the java command in the command line, specifying the name of the class containing the main method.<\/li>\n<\/ol>\n

    For example, a simple Java application may include the following main method:<\/p>\n

    public<\/span> class<\/span> HelloWorld<\/span> {\r\n    public<\/span> static<\/span> void<\/span> main<\/span>(String[] args)<\/span> {\r\n        System.out.println(\"Hello, World!\"<\/span>);\r\n    }\r\n}\r\n<\/code><\/pre>\n
    The program can be run by following these steps:<\/p>\n
      \n
    1. Save the above code as a file named HelloWorld.java.<\/li>\n
    2. To compile the file, use the javac command: javac HelloWorld.java<\/li>\n
    3. Execute the compiled class file using the Java command: java HelloWorld.<\/li>\n<\/ol>\n
      This will print “Hello, World!” in the command line.<\/p>\n","protected":false},"excerpt":{"rendered":"
