oops concept clarification

[Sisti Deb]

Hi,

Can anyone suggest me a good book for learning object oriented programming concepts- encapsulation,abstraction,polymorphism, inheritence.

I want to know like where it is implemented in java (particularly for abstraction), seen in many sites through google found only definitions and some raw examples.
Like for abstraction it is -- hiding the not required things and giving importance to the what is required. i want to know where we should see to realise thiese in java code,
if you say in abstract class then how...etc etc questions i want to clarify.
Kindly help me with books .

Thanks
sisti
