No. It's the variable that can't be changed. There is no restriction on the object a variable refers to.

That's wrong, the final keyword means that you can't reassign the variable. In case of methods, means that you can't override it. In case of Classes, means that you can't extend it.

You can find some good examples about final keyword here.

Hope this helps.
