To obtain a new class, programmers first find an existing class, and the new class is constructed based on this existing class, which we call inheritance. The derived class is called the subclass of the original class, while the original class is referred to as the superclass. Class inheritance is transitive: if B is a subclass of A and C is a subclass of B, then C is also a subclass of A.
