To K&B SCJP book team : Suggestions for the book

Subject : More examples and basics/theory of data-structures needed for the Collections chapter.

To the K&B SCJP book team,

The K&B SCJP book is good and is illustrated with simple/real-life examples which make it enjoyable to read. Most of the concepts are illustrated using simple but effective examples, like "the buckets" in the "understanding hashcodes" section.
However, it does not explain many things/basics related to data-structures (DS) in its collections chapter which can make it a difficult task to understand the same. For example, the descriptions of linked list, map, tree etc are brief/full of jargon and do not give a clear idea. This can be a major problem for non-CS students or for CS people who may need a refresher course.
I understand that the book is not meant to teach the basics of CS or java as mentioned in the preface. But the book would become more easy to understand and self-sufficient if a primer on DS was provided in the book/CD (current CD uses only ~40mb !) or in a companion website.

thanks and regards
rb.

PS : How about a head first Data-Structures and algos using java ? Such a book will teach the basics in a more beginner-friendly way and prepare the reader with the ability to digest "dry" and esoteric books, some of which might have excellent content. Its too late for me, but if these suggestions are accepted, then the future test-takers might benefit immensely from them.


SCJP 6. Learning more now.

One more suggestion for a new product :

FLASH CARDS like the ones people use in the preparation for competitive exams.
These cards will state the crucial rules and traps of java, chapter wise. They may be implemented as only theory or as questions with answers at the back (so that you can revise the rule/pitfall and test yourself at the same time). Also, these cards will be convenient to carry around. If that is a problem, then they can make a mobile version too.

thanks for hearing.

Hi Guys,

Thanks for the suggestions. Here are some responses:

- HF Data Structures and Algorithms: this is a book we've been discussing with our publisher. Nothing has been definitely decided yet but it's a possibility. If and when it does become a real project, we'll let everyone at the ranch know.

- Flashcards: Kathy and I go back and forth on this one. There is a lot of evidence that it really helps the learner to make their own flashcards, as a part of the learning process. So, it's another possibility, we're still debating

hth,

Bert

The points 1 and 2 about hashcode() and equals() in page 586 could be mentioned in page 552 also (at the end of the "understanding hashcodes section") , for clearer understanding.
