Write a complete Java program called DrawSquare.java that reads a positive integer n from the command line, where n is at least 2, then prints out an n by n square made of asterisks * to standard out. Your program will print a usage message (see below) and quit if the number of command line arguments is not exactly one, if that argument cannot be parsed as an integer, and if that integer is not at least two. Several runs of the program are printed below.

Examples of Output.
