How to properly override clone method?

Question

I need to implement a deep clone in one of my objects which has no superclass.

What is the best way to handle the checked CloneNotSupportedException thr

Answer 1

The way your code works is pretty close to the "canonical" way to write it. I'd throw an AssertionError within the catch, though. It signals that that line should never be reached.

catch (CloneNotSupportedException e) {
    throw new AssertionError(e);
}
