Hello World!

Code Understanding

/* A program to show the purpose of comments Author: ComputerSirKiClass */

This is a multi line comment. Whenever we give a multi line comment we use /* (front slash-asterisk) in the beginning and */(asterisk-front slash) in the end. Multi-line commenting tags are also helpful to comment anything within a program code.

System.out.println(“Hello World”);//Method for output to console

Use of double front slash(front solidus) makes it a single line comment. Anything after double slash is ignored. // can not be used for inline commenting within the code.

Suggested Filename(s): HelloWorldC.java
