I can't think of any other generic way except of using reflection
to traverse the member variables. But that's pretty hacky, and
slow as well ...
【在 r*****u 的大作中提到】
: without using Object.clone()?

BTW, it just occured to me that if you don't care about the color
of the object, then a regular office copier might work very well...

The problem of using reflection is that you can not copy the
private field of the superclass.

This only applies to serilizable object, right?

first, it depends on what "copy" means here. does your "copy" here mean
creating another object without calling its constructor?
generally, if you don't like the generic Object.clone(), why not
override it? You can provide your own way of "copy" in this way.
