Write a 'main' method that examines its command-line arguments and

• calls the (static) method displayHelp if there are no arguments. Note that displayHelp accepts no parameters

• otherwise, 'main' calls the (static) method argsError if the number of arguments is less than four. argsError accepts the number of arguments (an integer) as its parameter

• otherwise, 'main' calls the (static) method processArgs, which accepts the command-line argument array as its parameter.

For your output:

displayHelp() should just print out the word HELP

argsError() should print out the number of arguments passed in.

processArgs() should print out a list of the args.
