The rules for overriding a method are as follows:
¡ The argument list must exactly match that of the
overridden method.
¡ The return type must exactly match that of the
overridden method.
¡ The access level must not be more restrictive than that
of the overridden method.
¡ The access level can be less restrictive than that of
the overridden method.
¡ The overriding method must not throw new or broader
checked exceptions

The rules for overloading a method are as follows:
¡ Overloaded methods must change the argument list.
¡ Overloaded methods can change the return type.
¡ Overloaded methods can change the access modifier.
¡ Overloaded methods can declare new or broader checked
exceptions.
¡ A method can be overloaded in the same class or in a
subclass.
