Arraylist problem

Hello, I have a problem with displaying an object from an arraylist. I keep getting the error for line 57 "The constructor Bubble1() is undefined", I'm not too sure why. My code is below although I haven't included the code for the Bubble1 class as I know that this works, however if anyone could find my mistake I would be very grateful!
