java 设计模式
设计面向目标软件比较艰难,而设计可复用的面向目标软件就愈加艰难。你有必要找到相关的目标,以恰当的粒度将它们归类,再定义类的接口和继承层次,建立目标之间的基本关系。你的设计应当对手头的问题有针对性,同时对将来的问题和需要也要有足够的通用性。23种设计模式汇集(Java),经典文献。java设计模式.pdf
(Designing object-oriented software is more difficult, and designing reusable object-oriented software is even more difficult. It is necessary for you to find the relevant objects, classify them with the proper granularity, define the interface and inheritance hierarchy of the class, and establish the basic relationship between the objects. Your design should be specific to the problem at hand, yet general enough to future problems and needs. A collection of 23 design patterns (Java), classic literature.
