Instead of emphasizing the underlying mathematics to get programmers to build their own data structures, Collins enables them to manipulate existing structures in the Java Collections Library. This allows them to learn through coding rather than by doing proofs. 23 lab projects and hundreds of programming examples are integrated throughout the pages to build their intuition. The approach this book takes helps programmers quickly learn the concepts that underlie data structures.
Well-written book on data structures in Java. I already knew Java and OOP before reading, so I'm not sure if the intro to these concepts in the beginning is adequate for newbies or not.
As for the actual data structures: it covers all of the ones you need to know for a 2nd-year course. The code examples and exercises are helpful, though some of the code examples are kind of long. The diagrams, which are quite simple, are helpful in understanding how the data structures work.
