book to learn and know Object-oriented concepts

[Gajendra Kangokar]

Hi
I have been coding in java for more than 2 years now,
In recent interview I was asked questions on concepts of object oriented programming,
I was unable to answer and define properly.Only then I realized I do not know OOPS concepts thoroughly.
Please can anyone suggest a book to learn and know concepts of object-oriented programming.

Thank You

If you look in our book review pages, you will find conflicting opinions about that book. I didn't like it myself, but the more recent edition got a better review.

Since that is quite an old book, second‑hand copies will be available for a low price: about $12 (excluding carriage) on a well‑know books website.
