/**
 * Chapter 3: Excercise 2
 * An object of class LettingAgent maintains data and produces reports
 * useful in managing the business of a letting agent that arranges 
 * the rental of homes of various kinds with between 1 and 5 bedrooms.
 */
import java.util.ArrayList;
public class LettingAgent
{
    /** NOTE: The following fields are essential, but NO MORE fields should be added */
    private String tradingName;  // Business name of the agent Ð to appear in printed reports
    private ArrayList<Home> available;  // To hold the homes currently available for rent
    private ArrayList<Home> let;        // To hold the homes currently let (rented out)
 
    /** Constructor to initialise a newly created LettingAgent object 
     *  The parameter supplies a business name for the agent.
     */
    public LettingAgent(String name)
    {
[B]        /** Entre Code */[/B]
    }
 
    /** Method to add a home to the collection of those available to let.
     *  -- The number of bedrooms must be in the range 1 to 5.
     *  -- The specified address must be different from the address of any home already
     *     in the list of homes available for letting.
     *  If either condition is not satisfied, an error report should be printed.
     *  If the conditions are satisfied, the home is added to those available to let, 
     *  and a fully detailed confirmation is printed.
     */
    public void makeAvailable(String address, String kind, int bedrooms, int rent)
    {
[B]        /** Entre Code */[/B]
    }
