This tutorial provides all the steps required to install the Oracle Java 13 officially distributed by Oracle for Window. It provides the steps required to install Java 13 on Windows 10. The steps should be the same for other versions of Windows operating system.

Now click on Environment Variables, select Path under System Variables section and click on Edit. We need to add the path of installed JDK to system Path.

class HelloWorld {

public static void main( String[] args ) {

System.out.println( "Hello World !!\n" );
}
}

Now open the command prompt and navigate to the path where you have saved your Java program. Use the below-mentioned commands to compile and execute the program.
