And there is a book for that (though it may be outdated) from O'Reilly.
If you have to ask whether such a thing exists though, you probably wouldn't benefit from it (nor need it).

You can't. What's good in some cases may be bad in others.
You're looking at micro-optimisation, which is almost always bad.

We've seen worse, far worse.

Java Programming Book Recommendation

I'm looking for a good java programming book that covers more than the basics. In my CS110 class we went through the book:

by: D.S. Malik
I'm looking to expand upon this and was hoping someone was able to point me in the right direction of reading material.
Thanks!

Some comprehensive java's book?

Hello,
I was wondering does anybody can recommend to me some latest edition of some comprehensive java's book?
I'm studying from many year-two old books, and today I find one which contain significant improvement regarding the books I have.
So please, if anyone could give me some reference (book name, authors, etc...), I'll be very thankful !

Can anyone recommend a Java 3D Book

Can anyone recommend a Java 3D Book. What I'm looking for is one that isn't too expensive below �30 ($40) and is quite uptodate with the new 3D API. Or is there a book that is coming out soon, which is said to be good.
Thanks

I looked for 3d book, there are not that many in bookstores, bought one "Ready-to-Run Java 3D" Wiley by Kirk Brown and Daniel Petersen.
It's friendly but not very good at explaining things. Tutorials here on the site is much more helpful with simple but very useful examples.
I wish I did not spend money on the book.

Java 2D books

hi frndz.
Just I have been developing my projects on desktop app, and web app,,,, but just for myself i want to learn JAVA 2d so can any one tell which good book is in the market for that...thanx

Java2D is an API that has changed very little (even though the underlying implementation has improved a lot) so this old book is still useful:

Procedure to make a Java address book

Hi all,
I am a java beginer . I am planning to make some small projects. My first attempt is an Address Book . I want to know what all are the things i have to know to make an address book in java.

Hi pals,
Thanks a lot for your valuable replies. But still I have to go through some more clarifications . how to connect through the embedded database like derby . Also how to make those data to be added in the database . I mean how to code those things.
I am just a beginner in java . I have lots of doubts . But right now pls help me in these problems that i have mentioned here.
Thanks and Regards
RahulWell if you really are new then you are jumping WAY ahead. You need to start at the beginning getting to know things liek variables, classes, objects, methods, scope, polymorphic behavior. You are IN NO shape to jump straight into database and collections before doing the basics. Java takes time about a year I would say if you are dedicated to get to where you are now... (databases).
Get a good book like Head First Java and do lots of basic code. I have an oudated book that taught me well about the very basics and the reason was it was FULL FULL of excercises.
Java Programming Comprehensive Concepts and techiques
Java Head First
and google.
So long as theres java 5 or 6 in the title you will do great.

New to Java-Need book that explains OOP concepts

Hi-
This as a great forum!
I have been programming in VB for a while and now I'm trying to learn Java. Can someone please tell me which book is best for learning concepts like objects, classes, visibility etc; Most of the books I have seen go too fast or do not cover enough detail. I would like to find something that has lots of examples (diagrams are nice) and covers OOP thoroughly.
Thanks!
Ken

The "Head First" books might be a good, gentle intro:

Nevermind, the issue was that my persistence.xml did not contain the following property:
<property name="hibernate.hbm2ddl.auto" value="create-drop"/>
Therefore, the tables were not being created upon deployment.
Still, I would expect to see entity beans listed in the WebLogic console.

Java Script Book

Can anyone suggest a good book for learning JavaScript? or better yet an online tutorial. I am already familiar with Java.

I prowled around Amazon and "Beginning Javascript" by Paul Wilton seemed to get better reviews- excellent, in fact. "Beginning" may be a little deceptive, according to one reviewer.
