Explanation / Answer

1. Composition represents what kind of relationship? => Has-A

2. Which of the following terms can be used to describe inheritance relationships between classes? => All of the above

3. Select the parent class.: Shape, Shape is parent because all other classes are child classes of Shape.

4. Which of the following is not a good example of a hierarchy that could be modeled by
inheritance?=> Prime numbers

5. Which of the following examples represent the "is-a" relationship in the parent/child format? => All of above

6. What is the result of over-using inheritance? => All of above. When inheritance is overused, we create system dependencies,unnecessary relationships, and harder to use code.

7. In object-oriented programming, inheritance is transitive; that means a child class inherits all the methods and fields of all its ancestors

8. Public is the least secure member access specifier.

9. Inheritance is only possible in object-oriented languages.

10. Which of the following is/are benefit(s) of using inheritance? => All of above
