Hello World Program in Eight Different Popular Programming Languages

This fact is true that Hello World program is the first program that a programmer writes when he/she start learning a new programming language. Today I thought that I should share the hello world program in different languages. A video is also added for easy understanding of the programs. Let’s take a look on these programs.

class HelloWorld

{

public static void main(String args[])

{

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

}
