  每一个用户自定义的类装载器在创建时被分配一个“双亲”parent类装载器。如果没有显示地传递一个双亲类装载器给用]]>https://blog.youkuaiyun.com/sureyonder/article/details/5707825https://blog.youkuaiyun.com/sureyonder/article/details/5707825sureyonderThu, 01 Jul 2010 21:12:00 +0800工厂模式比较
1、简单工厂模式
 简单工厂模式的特点是一个工厂生产一个类型的产品。
 简单工厂模式又可以叫做静态工厂方法模式，简单的来说就是由一个工厂对象来决定创建出哪一个具体的产品类的实例。其类图如下所示：


工厂类（Creator）包含一个或者多个静态工厂方法，每个静态工厂方法会创建一个新的具体产品的实例。乍看起来该模式跟单例模式很相似，其实它们还是有着很大的区别的，简单来说有三点区别：
A) 单例类的构造方法要求是]]>https://blog.youkuaiyun.com/sureyonder/article/details/5695420https://blog.youkuaiyun.com/sureyonder/article/details/5695420sureyonderSat, 26 Jun 2010 09:38:00 +0800https://blog.youkuaiyun.com/sureyonder/article/details/5695079https://blog.youkuaiyun.com/sureyonder/article/details/5695079sureyonderFri, 25 Jun 2010 22:54:00 +0800
  Swing组件设计使用了著名的MVC模型-视图-控制器体系结构。为了了解MVC体系结构与Swing组件的关系，我们来看一下如何设计一个表示按钮的组件，因为按钮的各个部分可以与MVC体系结构的3个部分对应起来。
  按钮在任意给定时刻，可处于启用和无效两种状态之一。很显然，按钮只有处于启用状态时才会响应点击。记录按钮状态是很有用的，视图需要根据按钮的状态进行不同的渲染。按钮的所有状态就是MVC体系结构的模型部分。模型还包]]>https://blog.youkuaiyun.com/sureyonder/article/details/5682087https://blog.youkuaiyun.com/sureyonder/article/details/5682087sureyonderSun, 20 Jun 2010 19:41:00 +0800https://blog.youkuaiyun.com/sureyonder/article/details/5653609https://blog.youkuaiyun.com/sureyonder/article/details/5653609sureyonderMon, 07 Jun 2010 17:56:00 +0800https://blog.youkuaiyun.com/sureyonder/article/details/5633647https://blog.youkuaiyun.com/sureyonder/article/details/5633647sureyonderSat, 29 May 2010 21:09:00 +0800https://blog.youkuaiyun.com/sureyonder/article/details/5569617https://blog.youkuaiyun.com/sureyonder/article/details/5569617sureyonderSat, 08 May 2010 13:32:00 +0800https://blog.youkuaiyun.com/sureyonder/article/details/5569366https://blog.youkuaiyun.com/sureyonder/article/details/5569366sureyonderSat, 08 May 2010 11:26:00 +0800https://blog.youkuaiyun.com/sureyonder/article/details/5564181https://blog.youkuaiyun.com/sureyonder/article/details/5564181sureyonderThu, 06 May 2010 18:13:00 +0800https://blog.youkuaiyun.com/sureyonder/article/details/5560538https://blog.youkuaiyun.com/sureyonder/article/details/5560538sureyonderWed, 05 May 2010 17:54:00 +0800https://blog.youkuaiyun.com/sureyonder/article/details/5546197https://blog.youkuaiyun.com/sureyonder/article/details/5546197sureyonderFri, 30 Apr 2010 14:26:00 +0800https://blog.youkuaiyun.com/sureyonder/article/details/5542411https://blog.youkuaiyun.com/sureyonder/article/details/5542411sureyonderThu, 29 Apr 2010 14:03:00 +0800https://blog.youkuaiyun.com/sureyonder/article/details/5536243https://blog.youkuaiyun.com/sureyonder/article/details/5536243sureyonderTue, 27 Apr 2010 20:35:00 +0800
