Thread: Subclass/Interface problem

Hi there im having a bit of a problem, I have a House class which contains an arraylist of rooms(Room class). There is also a Property Menu class which asks the user to choose between a range of options .ie add a house. Eventually the user will be asked is the house for sale when adding a house.

The part of the task I am having trouble with is this:

Create a subclass of House called HouseForSale. Houses for sale have a guide price variable. Implement a zero-argument constructor for creating saleable houses interactively. Also overload toString().

I've created the subclass and the giude price variable. In the constructor should I put in a scanner to read in the room information then put it it an House arraylist called i.e housesell?
