1. Object,看Pattern接口的两个方法参数都是Object,这就意味着抛弃了类型安全 2. 只有基本的匹配,没有extractor,无法解构ADT,提取内容,比如对JDK自带的Optional类型的处理 先解决第一点,最关键的问题,去除Object,那必然会引入类型参数了,即:使用到Java Generics,并且保证type-safe ...

Java 空对象设计模式(Null Object Pattern) 讲解 有时候我们的代码中为避免 NullPointerException 会出现很多的对Null的判断语句,而这些语句一旦多起来,我们的代码就会变的惨不忍睹,因此我们引入了空对象模式(null object pattern)以此来使我们的代码变的更优雅一点。
Observer. This article describes the Observer design pattern and its usage in the programming language Java. 1. The Observer Pattern 1.1. Definition The Observer Pattern defines a one-to-many dependency between objects, so that when one object (the subject) changes its state, all registered ...

The intent of the Builder design pattern is to separate the construction of a complex object from its representation. By doing so the same construction process can create different representations. 将一个复杂对象的构建与其表示分离,使得同样的构建过程可以创建不同的表示 使用场景 这个就非常重要了,因为如...
