Assignment Task :

B. Project Details 

B(i) – Background information and description 

When people sell property, many employ a real estate agent to help them sell their property. Real estate  agents will charge the vendor a marketing fee and a commission (a percentage of the sale price if the house  is sold).  

You are required to write a Java program that will allow a real estate agent to manage records of vendors,  properties, and financial information related to sale prices, marketing costs, and commissions. Your Java  program will need to generate reports which provide summaries of financial data and past property sales meeting specific search criteria.  

In this assignment, your task is to create an object-oriented, menu-driven Java program that implements a  limited set of functionalities (i.e., the program will not be a complete real-world implementation) that a real  estate agent can use to manage their records of vendors and properties, as well as financial information 

related to the sale (or attempted sale) of properties. Your program will need to generate reports and retrieve  and save data in secondary storage. 

In general, your program will need to read data from the keyboard and from certain text files in secondary  storage, store the data in appropriate data structures using objects, sort and search the data, and write  output data to both the screen and to secondary storage. The specific functional requirements are described  in section B(ii) of this document. The text files that are to be used for this assignment are described in  section B(iii). The classes that must be used as a minimum are described in section B(iv). 

B(ii) – Program Requirements/Functionality 

The Java program must 

a) be object-oriented utilising the classes described in section B (iv) as a minimum. Other classes can  be created to solve the program requirements. 

b) be menu-driven. The main menu must have the following menu items: 

1. Display Properties. 

2. Record a new “Property ‘For Sale’”. 

3. Record a property as “Sold”.  

4. Generate “Financial Report”.  

5. Generate “Similar Property Report”. 

6. Save Data. 

7. Exit Program. 

c) be able to process the defined text files. The text files and their formats are described in section B  (iii). 

Program Start Up 

When the java program starts it must perform the following file related operations: 

a) Read the data from the vendors.csv text file into computer memory into an appropriate array of  Vendor objects (see section B (iii) for a description of the vendors.csv text file and section B (iv) for  a description of the Vendor class). 

d) Read the data from the properties.csv text file into computer memory into an appropriate array of  Property objects (see section B (iii) for a description of the properties.csv file and section B (iv) for  a description of the Property class). 

e) Read the data from the sales.csv text file into computer memory into an appropriate array of Sale objects (see section B (iii) for a description of the sales.csv file and section B (iv) for a description of  the Sale class).
