I have a class with a lot of methods. I would like to group similar methods together in their own class, but all of the methods need to extend another class, ClassC. So I was thinking of having ClassA, which contains the first group of methods, extend ClassB, which extends Class_C, etc.
Is this inefficient in terms of runtime performance, or are they virtually the same?
Note: there will be hundreds of instances of this class running at once, so I would really not want to waste memory.
