problems with inherit and super methods

[3xus0u]

1. how can I inherit a method without overriding it so that the parent part of the code and the child part are executed?
2. how to call super method on child object without overriding?

in the examples, either creating one class, or more than two but with overriding parent methods ...........

your header is very easy to use with examples, but the problems encountered baffle me

hope for help
