如果你有一定的面向对象编程经验,你会发现其中某些设计模式你已经无意识的使用过

了 如果你是一个新手,那么从开始就培养自己良好的编程习惯(让你的的程序使用通用

的模式,便于他人理解 让你自己减少重复性的编程工作),这无疑是成为一个优秀程序

员的必备条件.



整个设计模式贯穿一个原理:面对接口编程，而不是面对实现.目标原则是:降低耦合,增

强灵活性.-If you have some object-oriented programming experience, you will find some of the design patterns you have used the unconscious　If you are a novice, so good from the start to develop their own programming habits (to make your program use common pattern easier for people to understand　to reduce repetitive programming your own work), this is becoming a prerequisite for a good programmer whole through a principle of design patterns: the face of interface programming, rather than face the realization. principle objectives are: to reduce coupling, increase flexibility.
