原型模式深浅复制

java.awt.Component 实现了 Serializable 接口， 所有Component的子类，包括Button、Scorollbar、TestArea、List、Container、Panel、java.applet.Applet以及所有的Applet的子类和Swing的子类都是可以串行化的。
java.lang.Throwable类实现了Serializable接口，所有的Exception和Error类均是可以串行化的。而流、所有的Reader和Writer以及其他的I/O类都是不可以串行化的。AWT和Swing、容器类、事件类都是可以串行化的。事件适配器类、图像过滤器类、AWT包中与操作系统相关的特性类都是不可以串行化的。原始类型的封装类中只有void类是可以串行化的。多数的java.lang包中的类是不可以串行化的。反射类是不可以串行化的。java.math中的类都是可以串行化的。压缩类都是不可以串行化的。
