Answer the following statements true (T) or false (F)

1) Superclass constructors are not inherited by subclasses.
2) A has-a relationship is implemented via inheritance.
3) A Car class has an is-a relationship with the SteeringWheel and Brakes classes.
4) When a subclass redefines a superclass method by using the same signature, the subclass
is said to overload that superclass method.

1) True.
2) False. A has-a relationship is implemented via composition. An is-a relationship is implemented via inheritance.
3) False. This is an example of a has-a relationship. Class Car has an is-a relationship with class Vehicle.
4) False. This is known as overriding, not overloading—an overloaded method has the same name, but a different signature.
