Please suggest me best java book which explains the concepts in depth. I want to dig in the concepts. I have read SCJP and found that book quite good. But now i want to read in depth.
I am not sure there is such a thing as a "best" book. You will have to look at the different offerings and see whose style suits you. I like Horstmann and Cornell, for example, but you might not like it.
Thanks Campbell.. Yes you are right that it depends on the style. I want to say that i need a book which covers concepts like threading, collections, inheritance in depth with good examples and with a practical approach.
