|Frequently asked to fresh graduates and less experienced.|
|Ans. 1. public is the access modifier that makes the method accessible from anywhere, static is the keyword that makes it accessible even without creating any object, void means it doesn't return anything , String args is the array of argument that the method receives.|
2. If we use main without the string args , it will compile correctly as Java will treat it as just another method. It wont be the method "main" which Java looks for when it looks to execute the class and hence will throw
Error: Main method not found in class , please define the main method as:
public static void main(String args)
3. Main is not a keyword but a special string that Java looks for while initiating the main thread.
