Java Application --
Card Thing App
// General Information
// ---------------------------------------------------
// File: CardThingApp.java
// Type: java application file
// Date: Monday Nov 8, 2000
// Name: Byron Bahr
// Line: Incremental Programming Challenge v6
// Application Description
// ---------------------------------------------------
/*
This is Programming Challenge #4, v6 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. This
Versions 6 displays only the percentages of pairs.
All intermediate data is not displayed
