java中克隆的使用

大多数情况下，如果需要被克隆的对象满足下面的例子套用就可以了，参见博客：

The first thing you should know about Cloneable is - don't use it. It is very hard to implement cloning with Cloneable right, and the effort is not worth it. Instead of that use some other options, like apache-commons SerializationUtils (deep-clone) or BeanUtils (shallow-clone), or simply use a copy-constructor.

See here for the views of Josh Bloch about cloning with Cloneable, which explains the many drawbacks of the approach.
