thanks for clear my confusion

Answer 2

Final classes. A final class cannot be subclassed. 
u can declare some or all of a class'smethods final. You use the final keyword in a method declaration to indicate that the method cannot be overridden by subclasses. The Object class does this—a number of its methods are final .
