cross class methods

[bilibytes]

What will determine if a method should use methods from the same class or from the upper class(the class related to it)??

You will only use internal methods if the data is not available from an already called upper-class method and, thus, you have to reproduce the whole content of that internet method.

is that true?

Please do not capitalise large sections of your post. It is consider shouting and goes against forum etiquette.

Could you please explain your problem more?

I'm not sure I get what your asking.
Could you give us an example?
