Core Java 2 Vol.1: Fundamentals (Addison-Wesley Object Technolo) [Englisch] [Taschenbuch]

I am an extremely experienced Java programmer and Ph. D. computer scientist. I write and teach courses and develop technical assessments, so it's important to me to keep up with language developments. While I've bought a great many Java books over the years, I've been neglecting Core Java for many editions, thinking it would no longer be of any use and being tired of repurchasing books. I'm part way through this one, and I am astounded at how much I am discovering, especially about Java 5 & 6 (even though I thought I knew all about their new features). I'm also enjoying the detailed comparisons with C++, as I used to use and teach that too. No matter how much you know about Java I would strongly recommend this book, if only to read all the well-delineated comments and clarifications that appear frequently. A particularly nice feature is that where portions of the API are summarized there are indications of the version in which the feature was added -- it helped reduce my feelings of chagrin when I read something surprising to find that it had been introduced in v6 or was a part of v5 I hadn't yet explored. Unlike so many other books this one provides meaningful and useful examples. I am eagerly anticipating the second volume.

"Core Java, Volume I - Fundamentals" is meant to teach Java to developers who already know another language. Or as they put it, "serious programmers ... with a solid background in a language other than Java." This is important as the book assumes a knowledge of programming concepts. As such, the authors can explain OO rather than how a loop works. The syntax diagrams and flow diagrams offer concise explanations.

This edition (the eighth of the book) covers Java 6. I liked that each section was updated to reflect changes to the languages. The authors didn't just tack on some chapters about the new features. They integrated features as they made sense. More importantly, they updated existing examples to reflect the way they would be written if they were initially written today. This gives the reader appropriate exposure as to when to use new features. At the same time, the authors point out what was added in Java 1.4 so you can use it with an older version. There was even a screenshot of Windows Vista in the getting started section.

The book is about 800 pages. Some of this is long classes and API extractions. The authors do highlight important code snippets with explanations first, so it is possible to skip these parts. I did like the feature of the API extractions that showed when methods were introduced.

The authors explain Java in practice well including caveats. There are a few carefully labeled sections that are quite advanced. (proxys and new classloaders.) This is definitely not just an intro book! There was a bit of premature optimization. I don't see a need to worry about whether ArrayList is efficient unless it is a problem. At the same time, it is important to know why things work the way they do.

I recommend this book if you are looking to learn Java or have only used certain pieces of it. Just be sure to read the TOC carefully as the authors branch out. For example, the inheritance chapter covers var args and reflection.

This is the latest edition and eighth round of the "Core Java" series of books. When it first came out in 1996 it had no competitors, and now alternatives abound, in particular the "Head First" series for learning Java published by O'Reilly and Associates. However, this is still my recommendation both for people who are learning Java and for those who are old pros and just want to catch up on what's new in the language. There are plenty of code examples, and the explanations are very clear as in the previous editions. This series always comes in two volumes - the fundamentals volume appears first followed by an "advanced features" volume a few months later. Both are usually worthwhile due to their comprehensive coverage of the language. The following is the table of contents for the eighth edition, not yet shown on the product page at the time I am writing this:
