1. Java – Hello World

public class HelloWorld 
 public static void main(String[] args) 
     System.out.println("Hello World"); 

In Java everything is class. Every Class resides in a .java file. As opposed to C where there are no classes.

Please note the “Public” keyword in 1st and 2nd line. Also notice “static” key word.

A “main” method is the entry point and that were code starts executing. In case of java a main method should always be static.

Please check “C – Helloworld” for the “void main” explanation .
