This is a handy pocket reference/guide for the intermediate or advanced programmer. All materials are well-organized and illustrated with concise examples of code. It is “worth it’s weight” and should be on every Java programmer’s reference bookshelf.

I don’t know about you, but when I’m confused about something, I’m really confused. I need an example to clear up my confusion or my memory. This book gives examples in the most superficial of terms. It is designed to be a quick guide to J2SE through the Java 6 Platform, and quick is what it is. It is not going to jump start you if you need a real jump start on an issue you have forgotten. The most useful information is at the very end of the guide where it talks about the Java Scripting API, tools, and UML. The first half of the book is oriented towards the Java programming language and the second half is about the platform components and some special topics.

If you need useful examples in an accessible format I still suggest the Core Java books by Cornell. They may be somewhat unwieldy to lug around on trips, but they get the job done. Java Examples in a Nutshell is somewhat outdated, but it still can clear up some questions on parts of the language that haven’t changed over the years. If you are new to Java I absolutely recommend against getting this pocket guide. You’ll be lost. I include the table of contents since it is currently not listed in the product description.
