说明：  Java设计模式》面向有一定Java语言基础和一定编程经验的读者，重点探讨在Java程序设计中怎样使用著名的23个设计模式。《Java设计模式》的目的是让读者不仅学习怎样在软件设计中使用好设计模式，更重要的是让读者通过学习使用设计模式深刻地理解面向对象的设计思想，以便更好地使用面向对象语言解决设计中的诸多问题。
(Java design patterns, "the basis for a certain Java language programming experience and some readers, focusing on the design of the Java program 23 how to use the well-known design patterns. "Java design patterns" is meant to allow readers to not only learn how to use well designed software design patterns, more importantly, readers learn how to use design patterns through a deep understanding of object-oriented design to better use for target language to solve many problems in the design.)
