This class inherits the instance variables and methods using the extends keyword. So when you go to make your House class, you will define it in the following way: 

public class House extends Residence
{
   // ...
}

Since this class inherits everything from Residence, you can call Residence's constructor when you go to make a new House. To do this, you use super().

This calls the base class (or superclass's) constructor. Since we will give House 4 rooms, 4 walls, and a washer, you will define House's constructor like this: 

public House()
{
   super(4, 4, true);
}

Since House inherits everything from Residence, you don't need to write any new methods at all! House has a propertyValue() and numWindows() method just like Residence because it is a type of Residence.

So, when you want to know the property value of a given House h, you would call: 

h.propertyValue();

Similarly, House can also use the toString from Residence: 

System.out.println(h);
