Java Application --
Card Thing App
// General Information
// ---------------------------------------------------
// File: CardThingApp.java
// Type: java application file
// Date: Monday Nov 13, 2000
// Name: Byron Bahr
// Line: Incremental Programming Challenge v4
// Application Description
// ---------------------------------------------------
/*
This is Programming Challenge #4, v4 designed to
provide practice in writing Java programs using
Incremantal Programming techniques. The program
will read 50 pairs of playing cards then determine
and display characteristics of the pairs. Printing
"R" for the same Rank, "S" for the same Suit, and
"*" if neither Rank nor Suit are the same. Version
4 uses code featuring Boolean Logic to determine the
color of the cards. The output prints the color RED
if both cards are red, and Black if both cards are
black in addition to the previous descriptions.
