Solution 1

Very little, as the second object is merely a reference to the first. If you want a copy of the first element then you need to use the clone()[^] method.

"First element" does not explain what's really going on. You probably mean the notion of shallow copy, when the members are copied as references, so there is not recursive (deep) cloning; anyway, it need some explanations.

That's why I added the link to the clone() method.
