**课程名称：Java设计模式疑难解答** **课程概述：** 本课程探讨了已有二十余年的设计模式在软件开发中的重要性及其争议。课程将引导您学习如何运用设计模式使Java代码更加灵活、简洁和易读。核心在于“灵活性”，您将学会如何在形式化分析需求的特定“弹性轴”后，决定何时以及如何应用相应的设计模式。您将了解每种设计模式提供的具体灵活性类型，以及其在实践中最常见的实现方式，并学习如何规避和克服应用过程中的常见陷阱。 课程将通过一系列实际演示，逐一讲解设计模式。每个演示都从一个面临新客户需求引入困难的现有代码实现开始，经历一系列设计尝试——有些注定失败，有些则有成功的可能。最终，您将发现，每一次成功的重构都会体现出一种特定的、关键的灵活性，从而满足了客户的棘手要求，而这种特定的灵活性正是某种设计模式的体现。 **核心亮点：** * **理解设计模式的双重性：** 探讨其重要性与争议，帮助您形成独立判断。 * **掌握“灵活性”的本质：** 学习如何识别和应用设计模式来增强代码的弹性。 * **量化分析设计模式的应用：** 通过“弹性轴”的概念，科学地选择和应用模式。 * **实践驱动的学习：** 通过具体代码演示，理解模式的演进和应用场景。 * **规避常见陷阱：** 学习如何避免在应用设计模式时遇到的问题。 本课程适合希望提升Java代码质量、解决实际开发挑战的开发者。
More than two decades since design patterns have appeared, many developers consider them the most important discovery in software development. Others still find them a bad idea. And both are right! How comes?In this course, you will learn how design patterns can be applied to make code better: flexible, short, readable. Flexibility is the key element in design patterns. You will learn how to decide when and which pattern to apply by formally analyzing the need to flex around specific axis. You will learn which pattern is adding which kind of flexibility, and what are the most common forms of implementation in practice. You will also learn common pitfalls and ways to overcome them when applying specific patterns.Through a series of demonstrations, you will learn one design pattern at a time. In each demonstration, we shall start from an existing implementation which faces difficulties to accommodate the next requirement proposed by the customer. That will invariantly trigger a series of designing attempts, some doomed to fail, others having prospect to succeed. But what will learn in this course, is that each successful design will exhibit one kind of flexibility, which will be of critical importance to support the troublesome request posed by the customer. It will come as no surprise to you to learn that each such special kind of flexibility will be one specific design pattern.
