Create the following classes along with the specified instance data and methods. Make sure you use /** Javadoc comments */ to comment all public classes, constructors, and methods (with the @author, @version, @return, and @param tags as appropriate). Make sure the constructor validates data as specified. All constructors and mutators must throw an IllegalArgumentException when parameters do not match the expected format (listed below). The main method must try/catch/finally every object creation. Make all data (including parameters) final if it is not expected/desired to change. Avoid magic numbers; e.g. use public static final double PI = 3.14 instead of simply using 3.14).

CLASS	INSTANCE VARIABLES	METHODS
Address	Unit number (String: must be one to four characters) Street number (int must be 0 to 999999) Street name (String: must be one to twenty characters) Postal code (String: must be either length 5 or length 6) City (String: must be one thirty characters)	Get methods for all instance variables toString() to display the state of Address objects
Property	Price in USD (double, must be positive) Address (Address, not null) Type (String: must be one of: residence, commercial, or retail) Property ID (String: must be one to six characters)	Property will be a supertype that will hold common fields and behaviors of the subtype. Get methods for all instance variables Set method for price toString() to display the state of Property objects
Residence (extends Property)	numberOfBedrooms (int: must not be less than 1) swimmingPool (boolean: indicates presence of a pool) strata (boolean: indicates if part of a strata)	Subtype of Property Get methods for all fields toString() for displaying the state of Residence types
Commercial (extends Property)	loadingDock (boolean: indicates if it has a loading dock) highwayAccess (boolean: indicates if easy access to a highway)	Subtype of Property Get methods for all fields toString() for displaying the state of Commercial types
Retail (extends Property)	squareFootage (int: the amount of floor space available) customerParking (boolean: indicates if customer parking is available.	Subtype of Property Get methods for all fields toString() for displaying the state of Retail types
AddressReader		public static ArrayList readAddressData(File file) throws FileNotFoundException: reads address_data.txt and adds Address objects to an ArrayList and returns it.
PropertyReader		public static ArrayList readPropertyData(File file) throws FileNotFoundException: reads property_data.txt and adds Strings (for each line) to an ArrayList and returns it.
Agency	Name (String, 1 to 30 characters) Properties (HashMap of properties; key is property id, value is a Property)	addProperty(property): adds the (non-null) property to the HashMap removePropery(propertyId): removes the property whose ID matches the parameter, from the HashMap getProperty(propertyId): returns the property whose ID matches the parameter, from the HashMap (or null if there is no match) getTotalPropertyValues(): returns the total amount in USD of all Properties getPropertiesWithPools(): return an ArrayList type properties or null if there are none getPropertiesBetween(minUsd, maxUsd): returns an array of properties whose price falls in the range specified by the parametersor null if there are none getPropertiesOn(streetName): returns an ArrayList of addresses which are on the specified streetor null if there are none getPropertiesWithBedrooms(minBedrooms, maxBedrooms): returns a HashMap of Residences (key is property id, value is the Residence) whose number of bedrooms falls in ther ange specified by the parametersor null if there are none getPropertiesOfType(propertyType): returns an ArrayList that holds the subtype specified in the parameter. Parameter needs to be case insensitive (e.g. commercial) and results displayed in the following format: Type: COMMERCIAL 1) Property 9999: unit #9 at 99 Gretzky Way T6V7H3 in Toronto (1 bedroom): $99999. 2) Property 678T: 1515 Main Street V8Y7R3 in West Vancouver (2 bedrooms plus pool): $4000000. 3) Property A1212: unit #7h at 1500 Railway Avenue V9V5V4 in Richmond (4 bedrooms): $840000. Note that the sample output above is exactly what should be returned for the data shown below; it must create similar sentence structures for any property of any type. Notice the capitalization of various parts of the string (see above) versus how it was stored (see below). If there are NO properties of the specified type the output must be as follows: Type: RETAIL getPropertiesWithLoadingDock(): returns an ArrayList that holds only Commercial properties that have a loading dock available getPropertiesWithHighwayAccess():returns an ArrayList that holds only Commercial properties that have highway access getPropertiesWithSquareFootage(int squareFootage): returns an ArrayList that holds properties where square footage is at least the parameter value. getPropertiesWithCustomerParking():returns an ArrayList that holds properties where customer parking is available. getPropertiesWithStrata(): returns ArrayList that hold only the Residences that are in a strata.
Assignment2 (main class)	Agency: reference to the Agency class	public void init() throws FileNotFoundException: This method gets the ArrayList and ArrayList from AddressReader and PropertyReader, and uses them to create subtype Objects and adds them to the Agency.HashMap properties public void doSearches(): This method provides the primary user interface through command prompts that will allow the user to choose which search operations to perform. See the Sample Interface below. Each search will display results to the console. public static void main(String[] args) throws FileNotFoundException: Will create an instance of Assignment2 and use that to call init() and then doSearches().
