    /*Explanation: http://www.code2learn.com/2011/11/public-static-void-mainstring-args.html
    -Why public (access modifier) ?
    Public means that this Method will be accessible by any Class(If other Classes
    are able to access this Class.) main( ) must be declared as public, since it must be called by code
    outside of its class when the program is started.

    Why Static ?
    The keyword static allows main( ) to be called without having to
    instantiate a particular instance of the class. This is necessary since
    main( ) is called by the Java interpreter before any objects are made

    Why void ?
    The keyword void simply tells the compiler that main( ) does not return a value.

    What does String args[] do?
    String args[ ] declares a parameter named args, which is an array of instances of
    the class String. (Arrays are collections of similar objects.) Objects of type
    String store character strings. In this case, args receives any command-line arguments
    present when the program is executed.
