Java Problems (Really Need Help!)

I keep getting errors in java and I don't know what to do. Everything looks fine. Could someone please help? Here's the applet I'm working on and below it are the error messages.
/**
* File: PetRockApplet.java
* Author:	 Jacob Harris (regular bonus, trying for honors, and
1 honors bonus)
* Programming: 1st Hour
* Last Modified: January 26, 2014
* Description: This applet creates, draws, finds the area, flips, and
* changes the color of pet rocks (oval & 2 rectangles
*	 with names).
