Question:

I tried to make it so that,if I pressed the right/left key, the sprite/Mario would face right/left. If I pressed the right key, he would face right. But for some reason, When I pressed the left key, he won't face left.

Don't use a KeyListener. Instead use <a href="http://download.oracle.com/javase/tutorial/uiswing/misc/keybinding.html" rel="nofollow">Key Bindings</a> which are more flexible and are used by all Swing components.
