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.
