    public static void main (String [] args) {

        System.out.println ("This Application Displays The Numbers 1 To 4 Using   "+"The System.out.println, System.out.print And System.out.prinf"+" Methods");

        System.out.println (); //displays a blank line

        System.out.println ("1 2 3 4"); //Print numbers 1 to 4

        System.out.print ("1 2 3 4\n"); //Print numbers 1 to 4

        System.out.printf ("%d%c%d%c%d%c%d\n", 1,' ',2,' ',3,' ',4); //Print numbers 1 to 4
