這本書並未對Java程式語言做討論，因為彷間這類的好書已經非常多了。本書著眼於其他Java書即從來沒有提到的議題。期望帶給您真正對Java的『深度歷險』，也希望眾多Java愛好者對這本書的回應，可以支持我整理出更多有趣的議題。-This book does not do the discussion on the Java programming language, such as books between imitation very much. Book looks at the other Java books that never mentioned the issue. You really expect to bring Java-depth adventure 』『 also hope that many Java enthusiasts in response to this book, you can support my more interesting issues sorted out.
