Java noob problem

[NOBEL]

I am learning how use the ActionListener, I created a program that allows you to switch the screen from red to blue to yellow.
After I implement the Action Events (ae) I get one error.
Can anyone explain why I am getting that error and how do I fix it.

Code is below

It is a general practice that you dont make the frame class in itself an acionListener.

The way I usually attach actions to things is below

It would also help if you post what exact error you are getting.
