JAVA

You have been hired by the company Find Me A House Fast. Your job is to produce a list of real-estate listings that meet a client's criterion. You have a list of real-estate listings from the companies: Century 21, ReMax, Mc Enearney and Long & Foster. The home buyer first chooses the real-estate companies he wishes to use. The home buyer then can choose one of the following criteria: Style, Number of Bedrooms, Lot Size, Age, Price, Distance from Work, and Jurisdiction. Given a criterion and the list of real-estate companies, your job is to create a list of home listings from the chosen companies that satisfy the chosen criterion. You have a list of home listings from each real-estate company from which to choose. Think of possible classes that would be appropriate for this project.

Everything needed is in the link. You do not need the temperature and fraction demos. This program reads the text files Let me know if more info is needed. Thanks.
