Java First Program "HelloWorld"

// Outputs "Hello, world!" and then exits
public class HelloWorld {
   public static void main(String[] args) {
       System.out.println("Hello, world!");
   }

 In this program, we are defining the class HelloWorld. And the file name should be HelloWorld.java. This simple program only contains a single line to print "Hello, world!".
 And every program should contain a main class to execute the program.

In : Java
