- 1. Draw the class diagram for superclass and subclassarrow_forwardA subclass must fully implement all of the abstract methods of its parent class in order to be considered a subclass of an abstract class. What are your thoughts on whether or not it should be done?arrow_forwardWe spoke about base classes and derived classes in this part. What is the difference between the general and specialised classes?arrow_forward
- Explore the role of the "super" keyword in method overriding. How is it used to call a superclass method from a subclass, and why might it be necessary in certain scenarios?arrow_forwardWith appropriate examples, explain the features of static class members.arrow_forwardFor this problem you are to join the following classes into a hierarchy (use the UML diagrams from Module 2 to get started): Player - Super Class Archer - Subclass Barbarian - Subclass Cleric - Subclass Rogue - Subclass Warlock - Subclass If the parent class has the same attributes as the sub class then you can remove those attributes from the subclass. If the class is new for this module, please come up with 2 unique attributes of your choice, and 1 piece of functionality. If the sub classes are shown on the same level, then they share a parent class.arrow_forward
- Examine the role of access keywords in defining class members.arrow_forwardB and C are its subclasses, and A is the parent class. Now, B and C have certain similar features and methods, but B and C implement a number of their methods very differently. Use logic to specify if A is a concrete class, an abstract class, or an interface.arrow_forwardIn what kind of situation would you want to use an abstract class instead of a base class?arrow_forward
