Programming techniques may include features such as data abstraction, encapsulation, messaging, modularity, polymorphism, and inheritance. Many modern programming languages now support OOP, at least as an option. 面向对象程序课程设计 面向对象程序设计是当今软件设计开发的基本思想、方法与技术。本课程的目的是与面向对象程序设计课程教学相配合，强化读者面向对象程序设计的实践训练，从而领悟面向对象方法与技术的精髓。 程序设计是一门实践性很强的课程，它还是一门艺术，没有标准答案。从软件开发目标的确定、对象数据和功能的抽象、程序代码的具体组织，到一些很具体的代码编写技巧，程序设计是一个极具创造性的过程。在设计开发的路上，有多种选择，因而课程设计自始至终都需要编程者大胆创新。 面向对象程序课程设计 编程没有标准答案，但程序需要追求美。尽管程序的“美”没有标准答案，但仍然有一个大多数一流软件人员认可的评判框架。为写美的程序改进支撑技术，是软件界多年来的一个努力方向。具体到一个实际的程序，美也是一个可以不断改进的追求。正是基于这样的理解，本课程进行案例的“讨论”，旨在传达这样一个理念，编程是一个需要大家共同感悟的美妙过程。 面向对象编程思想与Java语法内容是相当庞大的一套体系。本课程不是面面俱到地讲授Java的具体内容，而是通过案例来讨论面向对象编程中的一些要点。案例是渐进式展开的，因此接近于实际编程中的逐步求精和迭代过程，目的是使读者感受到面向对象编程技术的精彩之处。 Erich Gamma, Richard Helm, Ralph Johnson and John Vlissides with a foreword by Grady Booch Challenges of object-oriented design are addressed by several methodologies. Most common is known as the design patterns codified by Gamma et al.. More broadly, the term design patterns can be used to refer to any general, repeatable solution to a commonly occurring problem in software design. Some of these commonly occurring problems have implications and solutions particular to object-oriented development. Abstract Factory groups object factories that have a common theme.
