// This program checks whether two words rhyme (end with the same 2 letters)
// or alliterate (start with the same letter) using String objects.
//
// This is an updated version of a program from a previous lecture, modified
// to use boolean methods for whether two words rhyme or alliterate.
// (Look at how clean and readable the main method has become!)
