A property management company manages personal rental properties and charges them a management fee as the percentages of the rent amount. Write an application that lets the user create a management company and add the properties managed by the company to its list. Assume the maximum properties handled by the company is 5.

Write a Data Manager Class named ManagementCompany that holds a list of properties in an array structure. This class will have methods to add a Property object to the company list, find property that has the highest rent amount, find the total rent of the properties and show the information of all the properties and the management fee earned by the management company. Follow the Javadoc file provided.

Write a Data Element Class named Property that has fields to hold the property name, the city where the property is located, the rent amount, and the owner's name, along with getters and setters to access and set these fields. Write a parameterized constructor (i.e., takes values for the fields as parameters) and a copy constructor (takes a Property object as the parameter). Follow the Javadoc file provided.

A driver class is provided that creates rental properties to test the property manager. You are also to write a Graphical User Interface using JavaFX which duplicates this drivers functionality. You are not required to read in any data, but the GUI will allow you to enter the property management company and each property by hand.

Operation

When driver-driven application starts, a driver class (provided) creates rental properties, adds them to the property manager, and prints information about the properties using the property managers methods.

When the GUI-driven application starts, a window is created as in the following screen shots which allows the user to enter applicable data.The driver and the GUI will both use the same classes for their operation.

The JUnit test class also tests the same classes as the driver and the GUI.

Specifications

Data Element -Property

The class Property will contain:

Instance variables for property name, city, rent amount and owner. Refer to JavaDoc for the data types.

toString method to represent a Property object.

Constructors (a copy constructor and parameterized constructor) and getter and setter methods.

Data Structure An Array of Property objects to hold the properties that the management company handles.

Data Manager ManagementCompany, this class should not have any output functionality (e.g., no GUI-related or printing related functionality), but should take input, operate on the data structure, and return values or set variables that may be accessed with getters.

The class ManagementCompany will contain the following methods in addition to get and set methods:

Instance variables of name, tax Id, management fee, MAX_PROPERTY (a constant set to 5) and an array of size MAX_PROPERTY of Property objects.

Method managementCompany Constructor pass in arguments for the name of the management company, tax Id and management Fee to create a ManagementCompany object.

Method addProperty Pass in a parameter of type Property object. It will add the Property object to the properties array. It will return the index of the array where the property is added or -1 if the array is full.

Method totalRent Returns the total rent of the properties in the properties array.

Method maxPropertyIndex- returns the index of the property within the properties array that has the highest rent amount. For simplicity assume that each "Property" object's rent amount is different.

Method displayPropertyAtIndex pass in the index of the Property object in the properties array and return the string representation of the property.

You may need additional methods to include in this class. Follow the Javadoc files provided.

User Interface Your graphical user interface or the provided PropertyMgmDriverNoGui.java are the only classes that interact with the user. The GUI will have the general structure of the below screen shots.

Expected output from running
