Why use final for classes and methods? One purpose is to improve security. If a method is final, it cannot be overridden in subclasses, ensuring that the behaviour of the method remains unchanged, thus improving security. Another benefit of defining a class as final is that it can improve efficiency. With a final class, type checking and binding can be done at compile time instead of runtime because the type and methods are already known and will not change.
