clone lists or objects

I want to copy/clone a list of Objects:

// copy reference

how can I copy the value instead of the reference?

Is that right?:

// copy Value instead of reference
s.setNames(new ArrayList<Name>(s1.getNames));

Or is there a other way?

That is the correct way to make a new ArrayList with the same contents of the list returned by getNames() - so yeah, copying the value. It does not create new Name objects inside the list, those values will still be shared between both lists.

I agree. Here's the link:
