设计模式
3-5 观察者模式实例之股票变化：某在线股票软件需要提供如下功能：当股票购买者所购买的某支股票价格变化幅度达到5%时，系统将自动发送通知（包括新价格）给购买股票的股民。现使用观察者模式设计该系统，绘制类图并编程模拟实现。
3-6状态模式实例之银行转账：在某银行系统中，我们定义了账户的三种状态：（1）如果账户(Account)中余额(balance)大于等于0，此时账户的状态为绿色(GreenState)，即正常状态，表示既可以向该账户存款(deposit)也可以向从该账户取款(whithdraw)。（2）如果该账户中余额小于0，并且大于等于-1000，则该账户的状态为黄色(YellowState)，即欠费状态，此时既可以向该账户存款也可以从该账户取款。（3）如果该账户余额小于-1000，那么该账户的状态为红色(RedState)，即透支状态，此时用户只能向该账户存款，不能在从中取款。现在用状态模拟来实现状态的转化问题，用户只要执行简单的存款和取款操作，系统根据数量自动转换到相应的状态。(Need to transport toBaiDu)

说明： 将一幅图像分成 SxS 个网格（grid cell），如果某个 object 的中心落在这个网格中，则这个网格就负责预测这个 object。(Divide an image into SxS grid cells. If the center of an object falls in the grid, the grid is responsible for predicting the object.)

TheMITPressConceptsTechniquesandModelsofComputerPr
一本非常好的计算机概念，技术和编程模型的原版书籍。(This innovative text presents computer programming as a unified discipline in a way that is both practical and scientifically sound. The book focuses on techniques of lasting value and explains them precisely in terms of a simple abstract machine. The book presents all major programming paradigms in a uniform framework that shows their deep relationships and how and where to use them together.
After an introduction to programming concepts, the book presents both well-known and lesser-known computation models ("programming paradigms"). Each model has its own set of techniques and each is included on the basis of its usefulness in practice. The general models include declarative programming, declarative concurrency, message-passing concurrency, explicit state, object-oriented programming, shared-state concurrency, and relational programming. Specialized models include graphical user interface programming, distributed programming, and constraint programming. Each model is based on its)
