I have seen a class has "is a" and "has a" relationship with one class. Is that a correct design? If it is correct, let me know the advantage of that design? On what scenario, we need to use this design?

The skeleton of the code :

Class A
  public void doSomeAction()  {}

Class B extends A
  private A obj;
  public void doSomeAction()
