I was looking for a latest edition of a book on data structures using Java. Lafore, Martin etc. are good texts but since collection API has introduced in jdk 1.2, those books seems to be obsolete. This book discusses new API and classes provided by java environment, so we need not to be bogged down by writing the unnecessary code. I feel this book is good for professionals in the industry as well as students of computer science. Algorithms are dealt with in detail with all the mathematical proofs involved, regarding efficiency and complexity. Various data structures are discussed with sufficient number of examples. Its a language specific book on data structures and algorithms, so if you are looking for a general book ar if you are working with any other language you will be dissappointed but surely a good book for java programming language.
