nullpointerexception - Receiving a java.lang nullpointer exception error in Processing -


I'm getting the java.lang nullpointer exception in my processing project, I think it's something with CDSTENCE, But I 'm not sure I have taken some stuff and still getting this error. If someone knows where I went wrong then it would be greatly appreciated.

 ball # update () ball # Calls Eclipse (), which has not been declared, and therefore is zero. You declare type ball holes and gables, but they are never started in the new ball. I suggest that you use an IDE such as eclipse or Inteliose, they make trivial bugs such that it is very easy to get rid of it, as well as post stacktrace the next time.
