当向集合Set中增加对象时，首先集合计算要增加对象的hashCode码，根据该值来得到
一个位置用来存放当前对象。

如果在该位置没有一个对象存在的话，那么集合Set认为该对象在集合中不存在，直接
增加进去。

如果在该位置有一个对象存在的话，接着将准备增加到集合中的对象与该位置上的对象
进行equals方法比较。

如果该equals方法返回false，那么集合认为集合中不存在该对象，再进行]]><![CDATA[Listener]]>https://blog.csdn.net/xiaodejun5241/article/details/5472590https://blog.csdn.net/xiaodejun5241/article/details/5472590xiaodejun5241Sun, 11 Apr 2010 13:43:00 +0800
