Hello, World! is one of the simplest programs used to understand the syntax of any new programming language.

Java Hello World Program

// Java Program to Print Hello World

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

Comments are used to explain code, and to make it more easily readable. Comments are ignored by the java compiler. Single line comments start with two forward slashes(//) and multi line comments start with /* and end with */.

public class HelloWorld{
	. . . . . 
}

In Java every application begins with a class, and in this program HelloWorld is the name of the class.

    public static void main(String[] args){
		. . . .
	}

Every program in the Java programming language must contain a main method.

        System.out.println("Hello, World");

This statement prints the message inside the quotation marks on the screen.
