Assume the existence of a Building class with a constructor that accepts two parameters: a reference to an Address object representing the building’s address, and an integer for the square footage of the building. Assume a subclass ApartmentBuilding has been defined with a single integer instance variable, totalUnits. Write a constructor for ApartmentBuilding that accepts three parameters: an Address and an integer to be passed up to the Building constructor, and an integer used to initialize the totalUnits instance variable.

CHALLENGE:

Assume the existence of a Building class with a constructor that accepts two parameters: a reference to an Address object representing the building’s address, and an integer for the square footage of the building. Assume a subclass ApartmentBuilding has been defined with a single integer instance variable, totalUnits. Write a constructor for ApartmentBuilding that accepts three parameters: an Address and an integer to be passed up to the Building constructor, and an integer used to initialize the totalUnits instance variable.

SOLUTION:

public ApartmentBuilding(Address address, int squareFootage, int    totalUnits) { 
   super(address, squareFootage);
   this.totalUnits = totalUnits;
}
