Java Project Summary:

The program should save and browse real estate properties of four

categories:

$-$ House: a single housing unit

$-$ Building: has an array of houses

$-$ Land: commercial or residential area

$-$ Agricultural land: for agricultural

The project should help users find information properties and it presents an estimated price for the properties.

Project detail:

$-$All information should be stored in a file, and it should be read from the file when the program starts.

$-$ The program should be organized according to the UML diagram below.

$-$ Note that RealEstate class is an abstract class and note the abstract methods it has

$-$ Comparison should be done based on property price $($net price$)$

$-$ Property prices should done as follows:

$1.$ Properties have different per$-$meter price according to the zoneCode.

$2.$ zoneCodes and the per$-$meter price for each type of apartment is saved in Prices class as parallel arrays. In other words, to get the price for a house in a zone X you find thehousePricePerZipCode at that index.

$3.$ After getting the price per meter square, it is multiplied by area in meter square to net price.

$4.$ For Apartments, price is increased by $5\%$ for top floor and bottom floor of a building.

$5.$ For Houses, price is decreased by $20\%$ if the house has more than one floor. And the price drops to $50\%$ if its older than $35$ years.

$6.$ Price for a building is sum of prices of all its apartment.

$-$ The driver class should provide the necessary to enter new RealEstates and Persons.

$-$ The Driver should allow user to either search from information about any property, or search for properties of a certain person.
