I will like to ask this question, but I don't know if is beyond the scope of this learning. it's about Gethashcode (), Tostring () Gettype () etc. I will like a little enligthment. The definition and overriding in a class, though I have gotten some definition, but I will like if someone could throw more light on it's usage.
