Head First Java

If you look at the Top 50 Books on Amazon in the Computers and Internet (C&I) section, you're

almost certain to find a "Head First Book" up there. Like most books, they bounce around in the

rankings, but if you've ever thumbed through a "Head First Book", you know that they deserve

that high ranking for one reason alone: "Head First" tosses the dry, technical learning book that

we all suffered through in programming class—and occasionally still suffer through—and replaces

it with something that's, well, just a heck of a lot of fun.

Hence, I had an ear-to-ear grin when O'Reilly sent me a free copy of the second edition of "Head

First Java" today. I had been looking forward to this book for quite some time. No, it wasn't such

a hot item that I could use it to barter some fence repair out of my neighbor, nor did I feel I had

the courage to ignore my family and plow through it in three nights like the first edition. Yet,

there's just something about those 1950s pictures that draws me in. The sheer audacity of

teaching computer programming using head shots of possible extras from the American

television show "Leave It To Beaver" just has to put a smile on your face. Did we really dress like

that 50 years ago? Not that I'm criticizing that dreamy-girl-with-the-soda that comes in every

once in a while and sets up the next lesson, but I can't deny this irresistible urge to put a "Gee,

Wally..." in front of every question I see at the end of a chapter. All in all, I guess I shouldn't

comment, since I look more like the nerd in the center of the cover.

There are a wide variety of books on learning Java. Arguably—and trust me, I will argue—the

best thing about this book are the figures. Almost every page comes with a number of great

visual metaphors to help you not only learn Java, but recall it later with eccentric fits of random

laughter while stuck in a meeting. Want a great reminder of how serialization and deserialization

works? Go no further than the table of contents for Chapter 14, where an inflated rubber-frog

intertube (deserialized) is pasted next to itself completely deflated, looking like the life has been

sucked right out of it (serialized). Want to know why inheritance isn't always a good thing? Try

asking the "doctor" on page 169, who inherited his knowledge so he didn't have to go to medical

school. Passing by copy instead of value? Let the depressed office worker making multiple

photocopies of his face help you remember which is which. And, of course, there's the

ever-present crossword puzzles that I even find my wife penciling words on in her spare time.

There's plenty of J2SE 5.0 material in this edition as well. For example, number

formatting—familiar to anyone who has programmed using the old printf() functions in C—gets

due coverage in Chapter 10. The enhanced for loop gets some text on page 105, and the all

important generics (in this case, with the Collections framework) gets a thorough treatment in

Chapter 16. Even the Java language itself on page 4 has morphed from a turtle (Java 1.0.2) ten

years ago to Lassie, to a proud horse (1.3), and then to some sort of "Iron Giant" Mech warrior

with Java 5.0. Once of these days, I'll have to ask the authors about that one.


Another nice thing about Head First Java, 2nd Edition is that it whets the appetite for more.

With later coverage of more advanced topics such as Swing and RMI, you just can't wait to dive

into those APIs and code that flawless, 100000-line program on java.net that will bring you

fame and venture-capital fortune. There's also a great deal of material, and even some best

practices, on networking and threads—my own weak spot. In this case, I couldn't help but crack

up a little when the authors use a 1950s telephone operator—yeah, you got it, that lady with a

beehive hairdo that manually hooks in patch lines—as an analogy for TCP/IP ports.


One final word: I need to disclose that I used to work for O'Reilly Media, Inc. as an editor, back

when it was called O'Reilly and Associates, Inc. That being said, I don't get any royalties from

this book (and boy I wish I did), nor am I rewarded for reviewing it in any way, shape, or form.

All I get is a free copy of the book, which is useful around income tax season since I can donate

the previous edition to my local library and add it to my itemized deductions. However, you

really should go to the bookstore and thumb through Head First Java, 2nd Edition. Even if you

already know Java, you may pick up a thing or two. And if not, just thumbing through the pages

is a great deal of fun.
