Hi there,

Null pointer exception is normally gotten when you forgot to initialise a variable. Even for object itself, it could be pointing to no where because you did not initialise any valid object to it. Eg, the Ball object has a Color attribute, but because you did not set anything for it and when you TRY to use getColor, it will throw a null pointer exception because it got nothing, not even a "" (space) is set.
