Having a bit of trouble with the logic of my program

I'm making a Billiards game for a project for my university. Right now I have a class named Ball that I use for both my cueBall and targetBall objects. Right now I have the variables centerX1 and centerY1 for the cueBall object and centerX2 and centerY2 for the targetBall object. I want to set the place x and y coordinates of where the mouse clicks the first time to be the x and y of my cueBall object. I want the second click to set the x and y coordinates for my targetBall object. I think the problem may have something to do with the parameters I'm initializing the objects of cueBall and targetBall with in setup(). Any suggestions on improving my code are appreciated. :)
