First Java Program

Lets run our first Java Program which displays "Welcome To Java".

import java.lang.*;

class First
{
//First is the name of the Class

//"What ever we type after "//" are known as 'comments' and they wont be executed while running your Java application."

public static void main(String args[])
{
System.out.println("Welcome To Java");
}
}

Note: 'void' never returns anything.
