New Java In A Nutshell Book

I've now got a new roach killer sitting on my bookshelf: O'Reilly's "Java In A Netshell, 5th Edition." And if you're a Floridian, you know how important having a good roach killer is. I've had a Java Nutshell book sitting on my bookshelf since 1.1. I never had one for 1.0 because Java was small enough to understand. I could use Javadoc exclusively to find everthing I cared to know.

The latest version weighs in at 1224 pages and covers the core part of the language. Compare this with the 4th edition, which stopped at a svelt 969 pages. The new version also returns to the use of marking each package section in the book, making it a lot easier to navigate to the package (and class) you're trying to look up. The 4th edition dropped the marking and annoyed quite a few programmers, some who recommended not bothering to purchase the book just on that one flaw.

The book is organized as follows:

Part 1. Introducing Java
  1. Introduction
  2. Java Syntax from the Ground Up
  3. Object Oriented Programming in Java
  4. Java 5.0 Language Features
  5. The Java Platform
  6. Java Security
  7. Programming and Documentation Conventions
  8. Java Development Tools

Part II. API Reference
  2. java.lang and Subpackages
  3. java.math
  5. java.nio and Subpackages
  6. and Subpackages
  7. java.text
  8. java.util and Subpackages
  9. java.crypto and Subpackages
  10. and
  11. and Subpackages
  12. java.xml and Subpackages
  13. org.w3c.dom
  14. org.xml.sax and Subpackages


The biggest change is chapter 4, "Java 5.0 Language Features." That 44 page section covers generics, enumerated types, and annotations. Other features new to Java 5 such as autoboxing, the for/in loop, varible length argument lists, covariant return, and the import static directive are covered in chapter 2, "Java Syntax from the Ground Up." The reader would do well to read both chapters and to pay attention to the examples.

Compared to the forth edition, it looks like JavaBeans have been dropped from the fifth edition. The fourth edition's chapter 6 and the java.beans package documentation (chapter 9) are gone. Another package dropped in the fifth edition is org.ietf.jgss (chapter 22 in the forth edition). One additional package dropped from the fifth edition was package documentation. The author covers these changes in a paragraph in the preface, and goes on to say:
JavaBeans standards have not caught on in core Java APIs and now appear to be relevant only for Swing and related graphical APIs. As such, they are no longer relevant in this book. The package has been deprecated since Java 1.2 and I've taken this opportunity to remove it. And the org.ietf.jgss package is of interest to only a very narrow subset of readers.
Still Relevant

In spite of its heft the Java Nutshell book still remains relevant. It's a lot easier to sit back and just read the material in a book. It requires no battery power or computer to just pull down the book and look something up. And the material has been slowly corrected over time. My only complaint is that a completely searchable electronic version isn't available to sit next to my development tools while I work. But with autocomplete in Eclipse and Netbeans even that need is no longer as vital as it would be if I were, say, working in just a text editor.

My only concern is where the dropped material will wind up. Coverage of the AWT and Swing were dropped in the forth edition and wound up in its own book. The only problem with that is the Swing nutshell book appeared on bookshelves a long time after it was needed. I'm hoping that the JavaBean material will wind up in the Swing book, and that the Swing book shows up fairly quickly.

A Decade Long Religious Con Job

I rarely write inflammatory (what some might call trolling) titles to a post, but this building you see before you deserves it. I've been seeing this building next to I-4 just east of Altamonte/436 and Crane's Roost for nearly 12 years, and never knew who owned it. Today on a trip up to Lake Mary with my wife I saw it yet again. That's when I told her I wanted to stop by on the way back and poke around the property, and photograph any parts of it if I could.

What I discovered was this still unfinished eighteen story (I counted) white elephant, overgrown with weeds and yet still under slow-motion construction. It looks impressive with its exterior glass curtain walls, but that impression is quickly lost when you see the unfinished lower stories and look inside to the unfinished interior spaces.

A quick check via Google leads to an article written in 2010 by the Orlando Sentinel about the Majesty Tower. Based on what I read in the article it's owned by SuperChannel 55 WA…

Be Careful of Capital One Mailings

Capitol One ("What's in your wallet?") sent me a bit of deceptive snail mail today. I felt sure it was a credit card offer, and sure enough, it was. I open all credit card offers and shred them before putting them in the trash. Normally I just scan the front to make sure I don't miss anything; the Capital One offer made me stop for a moment and strike a bit of fear into my heart.

The letter's opening sentence read:
Our records as of December 30, 2009 indicate your Capital One Platinum MasterCard offer is currently valid and active.Not paying close attention during the first reading, I quickly developed this irrational worry that I was actually on the hook for something important, but I wasn't quite sure what. The letter listed "three ways to reply" at the bottom; via phone, the internet, and regular snail mail. I elected to call.

Once I reached the automated phone response system, the first entry offered was '1', to "activate my Capital …

cat-in-a-box channels greta garbo

So I'm sitting at my computer, when I start to notice a racket in back. I ignore it for a while until I hear a load "thump!", as if something had been dropped on the floor, followed by a lot of loud rattling. I turn around and see Lucy in the box just having a grand old time, rolling around and rattling that box a good one. I grab the GX1 and snap a few shots before she notices me and the camera, then leaps out and back into her chair (which used to be my chair before she decided it was her chair).

Just like caring for Katie my black Lab taught me about dogs, caring for Lucy is teaching me about cats. She finds me fascinating, as I do her. And she expresses great affection and love toward me without coaxing. I try to return the affection and love, but she is a cat, and she takes a bat at me on occasion, although I think that's just her being playful. She always has her claws in when she does that.

She sits next to me during the evening in her chair while I sit in mi…
