Operation When driver-driven application starts (provided), it creates a property management company and some rental properties, adds them to the list of the properties managed by the property management company, and prints information about the properties using the property manager's methods When the GUI-driven application starts, a window should be created as in the following screen shots which allows the user to enter data for management company and its rental properties. The driver and the GUI will both use the same classes for their operation. The TUnit test class also tests the same classes as the driver and the GUI Specifications Data Element-Property The class Property will contain: 1. stance variables for property's name, city, rent amount and owner's name 2. toString method to represent a Property object. Refer to JavaDoc for the data types 3. Constructors (a copy constructor and a parameterized constructor) and getter and setter methods Data Structure An Array ofProperty objects to hold the properties that the management company handles Data Manager 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 1. Instance variables management company's name, tax Id, management fee, MAX PROPERTY (a constant set to 5) and an array of size MAx PROPERTY of Property objects 2. Method managementCompany Constructor-pass in arguments for the name of the management company, tax Id and management Free to create a ManagementCompany object. 3- 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 ifthe array is full. 4. Method totalRent- Returns the total rent of the properties in the properties array 5. 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. 6. 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 User Interface Your graphical user interface or the provided PropertyMgmD are the only riverNoGuijava classes that interact with the user.
