Recommend several books to learn Java

■ Java in a nutshell: a desktop quick reference, 2nd Edition, author: David Flanagan press: O'Reilly & Assoc, published in 1997 introduction: a brief summary of Java 1.1 online documents. Personally, I prefer reading documents online, especially when they change so fast. However, many people still like printed documents, which can save some internet fees. And this book also provides more discussion than online documents.

■ "the Java class libraries: an annotated reference" by Patrick Chan and Rosanna Lee Publishing House: Addison Wesley publication time: 1997 introduction: as an online reference resource, readers should be provided with enough instructions to make it easy to use. A technical reviewer of thinking in Java said, "if I can only have one java book, I must choose it." But I'm not as excited as he is. It's too big, too expensive, and the quality of the examples doesn't satisfy me. But when in trouble, the book is still of great reference value. Moreover, compared with Java in a nutshell, it seems to have greater depth (and of course more text).

■ author of Java network programming: elliote rusty Harold David Flanagan press: O'Reilly publication time: 1997 introduction: before reading this book, I can say that I don't understand java network related problems at all. Later, I also found that his web site "cafe au lait" is an exciting, personalized and frequently updated place, involving a large number of valuable java development resources. Because it is updated almost every day, you can see a lot of news about Java here.

■ core Java, 3rd Edition, author: cornel and Horstmann press: Prentice Hall publication time: 1997 introduction: if you can't find an answer to your problems in thinking in Java, this is a good reference place. Note: the version of Java 1.1 is core Java 1.1 volume 1-fundamentals & core Java 1.1 volume 2-advanced features

■ "JDBC database access with Java" Author: Hamilton, Cattell and Fisher press: Addison Wesley publication time: 1997 introduction: if you know nothing about SQL and database, this book can be a good starting point. It also gives a detailed explanation of the API and provides a "comment reference". Like all other books in the "java series" (the only series authorized by javasoft), the disadvantage of this book is that it exaggerates too much and only says good things about Java - there is nothing unfavorable to Java in this series of books.

■ author of Java programming with CORBA: Andreas Vogel and Keith Duddy press: Jonh Wiley & Sons publication time: 1997 introduction: this book describes in detail the three main Java orbs (visbrooker, Orbix, Joe) with a large number of code examples.

■ design patterns by gamma, helm, Johnson and vlisides press: Addison Wesley publication time: 1995 introduction: This is a classic book that initiated the scheme revolution in the field of programming.

■ UML toolkit by Hans Erik Eriksson and Magnus penker press: Jonh Wiley & Sons publication time: 1997 introduction: explain UML and how to use it, and provide practical cases of Java for reference. The companion CD-ROM contains java code and an abridged version of rational rose. This book gives an excellent description of UML and explains how to use it to build practical systems.

■ "practical algorithms for programmers" by binstock and Rex press: Addison Wesley publication time: 1995 introduction: algorithms are described in C, so they can be easily converted into Java. Each algorithm has a detailed explanation.
