Expert Solution

Question:
To make class DressShirt inherit the functionality of both Clothing and Shirt (from the previous question), the class header would be:
Ans: public class DressShirt extends Shirt, Clothing

Whenever we need to inherit the functionality of the classes, we need to use the keyword "extends"
Since we need to inherit the functionality of the two classes Shirt and Clothing.
We need to use the extend keyword followed by the class names that we need to implement as:
public class DressShirt extends Shirt, Clothing

Question:
If Shirt inherits Clothing, then Shirt has direct access to the ______ members of Clothing
Ans: public and protected

As a class inherits other classes, then the inherited class which is subclass has direct access to the public and protected members of the class Clothing which is the superclass.

Question:
Shirt inherits Clothing. What is the first thing that must happen in the Shirt constructor?
Ans: Call the Clothing constructor

The first thing that happens in the shirt class after inheriting the Clothing class is it will call the clothing constructor.
