Final Methods Cannot Be Overridden
A final method in a superclass cannot be overridden in a subclass—this guarantees that the final method implementation will be used by all direct and indirect subclasses in the hierarchy. Methods that are declared private are implicitly final, because it’s not possible to override them in a subclass. Methods that are declared static are also implicitly final. A final method’s declaration can never change, so all subclasses use the same method implementation, and calls to final methods are resolved at compile time—this is known as static binding.
