里面有Thinking in java 第一版（中文）、第二版（英文）以及很全的scjp認證資料 (最近可能有點問題）
http://person.longcity.net/home1/wenchund/index.htm
有JB5、JB6的破解碼以及為數不多的java電子書籍 （也有問題）
http://www.java-cn.net/book/index.jsp
這里書比較多，包括《Thinking in java》、《java2編程詳解》、《Jbuilder開發人員指南》、《Java程序設計技巧1001例》。。。還有一些簡單程序的源代碼
http://www.mindview.net/
這是《Thinking in java》作者的主頁，英文版的書也可以在這里下
