Title: 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. This concept will be explained...
Full Transcript: 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. This concept will be explained further in Chapter Five, which covers polymorphism and dynamic binding. Defining a class as final ensures that the type of the object and method binding are determined at compile time, thereby improving efficiency.
