Question:
Shirt inherits clothing. In the Shirt constructor, how is the Clothing default constructor called? (Select all that apply)
Ans:
super();

Here the class shirt inherits Clothing. Whenever we need to invoke the Clothing default constructor
We need to use the super() keyword in order to call the clothing default constructor.

Question:
Shirt inherits Clothing. In the Shirt constructor, how is a Clothing constructor with one int parameter called?
For the answer, assume that an int variable called "myInt" is in scope.
Ans:
super(myInt);

As mentioned above if there is no parameter we can simply use super()
If it is having an int parameter for the function call then we need to use super(myInt)

Question:
Shirt inherits Clothing. Both classes have their own version of the method fold(). Which fold() is executed in the following code?
Shirt myShirt = new Shirt();
myShirt.fold();
Ans: The Clothing version

This is the case of overriding rule, As per the rule we need to call the child class first since because of the static nature,
It is not possible to override the method and will call the Superclass which is Clothing. It will invoke the Clothing version.
