Query: Book is obsolete already!

This book would rate a zero except that some people might like to use Java 1.0. This book covers only Java 1.0 and while it came out in 1998? (copyright date is 1998, although it was supposedly published in November 1997) has no Java 1.1. The author even states in his preface that with Java 1.2 coming out and with the buggy development tools for Java 1.1 he decided to stick with Java 1.0. This means the book was obsolete before it was printed. Java 1.1 did have buggy development tools, but the database components that Java 1.1 had were critical to real database programming. Besides Java 1.1 has beans and jars which aid in the reuse of code. So while others struggled with Java 1.1, the author of this book took the easy road and produced an out of date book which for me has more use as a doorstop than as something to waste my time with.
