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
Or is there a other way?

That is the correct way to make a new
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.
It is sorta covered in the
