Java Cards

I was just messing around with Java and made a small GUI to push some cards around on the screen. Here is the source for the whole thing. card_test.zip I was mainly testing out the JLabels on a layered layout type scenario. Next I'll be working on a full fledged Solitaire app, but this is just messing around on the screen, more or less a HELLO WORLD with cards.


import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
