java.util.LinkedList has the removeLast() method out of the box...

You can use the removeLast() method from LinkedList. If your variable is of type List then this method will not be available, you may have to cast it back to LinkedList again/change the type to LinkedList

Is this homework? LinkedList in Java has a removeLast method with returns the element removed.

I hear a distant pop coming from a Stack ;)

Unfortunatly, Stack is a subclass of Vector and not of LinkedList (Hint hidden behind the last link ;) )

It will return the element removed.
