You must hand in a single file named Etch A Sketch java for your lab-07 submission. It will not (cannot be script graded. It will be checked for compilation success at handin time. You are to enhance this Etch A-Sketch,java program as follows: get rid of the x,y coodinate reporting. add a control that allows the user to change the drawing color (like Paint but can be MUCH simpler). a simple JButton that when clicked, toggles between 4 colors is sufficient
