If class B extends class A it is everything A is but has some other distinguishing features or abilities. As though you had a class MotorVehicle and class extending it such as Truck and Tractor.
If class B contains an A well, it has an A of it's very own. Like you have a class MotorVehicle that has as member data objects SteeringWheel mySteeringWheel and Engine myEngine.
