Like Manoj, I'm not sure what you mean, but there's source code for almost the entire SDK. However, I suspect it's likely to hinder rather than help.
The idea is to learn how to use classes, not know exactly what's inside them. You don't need to understand how an engine works in order to drive a car.

thanks in advance.

You can find a recommended hashCode method in Joshua Bloch's Effective Java™ or Bruce Eckel's Thinking in Java™ (TiJ); Eckel acknowledges Bloch there. You can find the 3rd edition of TiJ or a sample chapter of Bloch (old edition: try here) free of charge if you search the net. There are subtle differences in Bloch's recommendations in the 2nd edition.

That is what it means for a class to implement an interface.

I don't think so. For one thing I don't understand what "functionality usage" means.

Bear Bibeault wrote:The interface merely declares what methods are available -- it says nothing about the implementation. So having the interface on two classes in the hierarchy introduces no ambiguity.
It's like if a person says: "I'm a police officer. I'm a police officer." Just because he said the same thing twice doesn't mean there's more than one police officer.

Really? Is that what an interface means?
Think about it.
