Programmers can cut right to the chase and learn Java 1.2 fast with this fully-revised and updated edition of Just Java, Peter van der Linden's long-time best-seller! The new edition includes practical introductions to the important new features added to JDK 1.2, especially the graphical "Swing" components. Written in the author's trademark humorous style, it presents a crystal-clear introduction to both Java and object-oriented programming. You'll find extensive real-world examples, and expert insight into both the advantages and challenges of programming with Java 1.2. The accompanying CD-ROM is a truly awesome resource, including extensive sample code from several top Java programmers, the complete 121-page Java Programmer's FAQ, and tons of great freeware, including Linux, Samba, Perl, Tcl, Python, the Algol compiler, Java games, and much more.

Amazon.com Review

So, you're starting from zero in an effort to learn the Java programming language. What book will help you most? Just Java 2 should be on your desktop. It's one of a select group of introductory Java books that honestly earns its cover price.

Shying away from complicated aspects of the language that are seldom used in most practical situations, Peter van der Linden focuses his considerable teaching skills upon the parts of the language you really need to understand in order to be a good Java programmer. He covers basic structure and syntax very well, and gives similarly excellent attention to object orientation and the means by which Java implements it. Applets, Beans, input/output streams, basic graphics, Swing, and security all get superb coverage.

In short, this book explains everything you really need to know in order to write useful Java programs. With sharp text and very good example programs, the author shows you how to get things done. In the process, van der Linden--a funny guy--pauses often to show you how to make an origami water-bomber or comment upon software error messages like "runt packet."

The CD-ROM that comes with this book deserves much praise, as well. Packed with honestly useful tools and all of the author's examples, it employs a fine HTML-based interface that other books ought to imitate. --David Wall

Review

Read the full review for this book.

Just Java 2 is the fourth edition of Peter van der Linden's introduction to object-oriented programming and to the art of Java. It's aimed at intermediate programmers for whom Java shall serve as their baptism in object programming. In its category, Just Java is noteworthy, and is marred for this reviewer only by the author's injection of himself into his book.

I'll explain my criticism later in this review. First, let's talk about what's right with van der Linden's book.

Just Java is more than an author's striving for publication; it's semiofficial Sun pedagogy. This is part of Sun's attempt to make learning Java easy and grab more geek mindshare and heartshare. The lessons reflect pretty accurately what a Sun engineer feels is that portion of the truth about the Java language, the Java VM, the AWT, and Swing that the entry programmer must know at a minimum to begin to actually deliver some code. --Jack Woehr, Dr. Dobb's Electronic Review of Computer Books -- Dr. Dobb's Electronic Review of Computer Books

5.0 out of 5 stars Great reference/Great learning tool, December 24, 1999

By 

Lynn (Pittsburgh, PA USA) - See all my reviews

This review is from: Just Java 2 (Paperback)

It's not often that you find a book that can both teach you a new language and function as a great reference. This book is it. Aside from the JDK help, this is my only reference and for the most part it has served me well.

I started from a C++ background and had no trouble learning from this book. It might be tempting to skim through some of the beginning chapters that seem like something any C++ programmer would know (e.g. Object-Oriented Programming), but I recommend reading them. There are a lot of really good Java tips you don't want to miss, such as how constructors are invoked and how static blocks are loaded in the JVM.

Probably the biggest benefit of this book is that it tells you both the how and the why in many cases. Another positive is that the examples are small and to the point. In general there was a good amount of information per page.

The book's biggest weakness is the chapter on File I/O. This is common functionality that many Java programmers will use, but the presentation is not as easy to follow as the other chapters. Another drawback is the networking chapter, but there seem to be entire books dedicated to this subject.

If you are learning Java from an object oriented background, you will be glad you got this book. It's one of the thinner books on the shelf, believe it or not, but the information is top notch.

4.0 out of 5 stars A fun read for a computer book, January 8, 2000

This review is from: Just Java 2 (Paperback)

This book succeeded in getting me started with Java. I'm not a great programmer, so that's saying something.

Other reviewers have complained about the difficulty of picking up OOP concepts from this book. I can understand their point of view, but in van der Linden's defense I think it should be pointed out that OOP is fairly hard to get ahold of the first time you're exposed to it, and I'm not sure other books are much easier.

I studied math in college, and I found that I didn't learn things from the teacher as much as I did by wrestling with the problems on my own. If you want to understand why the main method in your class has to instantiate an object of the class that contains the aforementioned main method in order to access an object member that isn't static, you're going to have to work through it on your own. It's the sort of understanding that a teacher can't really hand you on a silver platter. It's not really hard, but you do have to know what all the words mean. The experience of wrestling with these kinds of concepts is what makes them sink in.

So I would argue that this book is complete, in the sense that it takes you through the OOP concepts you need to learn. But fundamentally you have to confront those concepts by yourself, alone in front of your own computer with your own copy of the JDK. If you try to run through the book without confronting the issues that fly over your head in the early chapters, the rest of the book will be incomprehensible. It's analogous to what happens to you in French class if you don't learn the early grammar and vocabulary.

I enjoyed the style of the book. Linden makes you feel like there's a human being on the other side of word processor, with a personality, a sense of humor, and his own style and sensibility. I wish more computer books were like that, so many of them are impersonal and devoid of human content. Spending time with this book is a little more like spending time with a person, which is a good thing in my opinion.

Part of Linden's personality is a fairly ideological approach to the computer industry. He's down on Microsoft and an evangelist for Java. I'm not sure that's a bad thing, but the anti-Microsoft stuff might rub some people the wrong way.

I think it's a great book overall.

2.0 out of 5 stars Not for true beginners, November 28, 1999

By A Customer

This review is from: Just Java 2 (Paperback)

I bought this book after reading the reviews. The impression I had was that this would be an excellent introduction to Java. What I discovered is that this book ASSUMES KNOWLEDGE OF C++. If you dont have some background in C++, then skip this and go for something else!
