Objectives
This assignment is designed to test the ability in defining superclass, subclasses and creating & using objects in addition to designing Graphical User Interface (GUI).
Assignment Task
CQ Real Estate (CQRE) has requested you to create a Swing based Java GUI application to cater their needs. Whenever CQRE receives a property sale offer from the seller, it assigns an employee exclusively to that sale offer and then lists it for sale. When the prospective buyers provide their offers for buying these properties, CQRE maintains the details of those purchase offers. You may note that there can be many purchase offers for the same listed property. Some of the purchase offers may be less than and some may be more than the seller's seeking price for a property.
The listed property details must include the following:
- Type of the property (house/unit/villa)
- Address of the property
- Area of the property (in square meters)
- Number of bed rooms, garages and toilets available in the property
- Details of principal owner (only one owner's detail even though there can be multiple owners to the same property)
The sale offer must include the following:
- Property details
- Date of Offer
- End date
- (Seeking) Amount
- Name of the employee assigned to the property sale offer
- Sale commission percentage
The purchase offer must include the following:
- Sale offer details
- (Offered) Amount
- Date of Offer
- Details of prospective buyer (only one prospective buyer's detail even though there can be many prospective buyers for one purchase offer)
The software application's GUI should have necessary controls that are necessary to receive the input data and the application should store them appropriately in arrays or ArrayLists or any other suitable structures. In the initial stage, in assignment 1, the application need not store the input data in text files. The application's GUI layout is left to your choice. The application should also be user-friendly and is expected to display appropriate error/exit messages. For the software application development, you have to create appropriate Java classes and you must use the inheritance concept of OOD. You need to create your own superclass and sub classes that are relevant to the above requirements. Please note that extending the available built-in Java classes such as JFrame will not be considered, as inheritance usage, for assignment marking purpose. The application should also show your Student ID and Full name.
The data type for each of the inputs has not been mentioned purposely. You need to use the appropriate data type accordingly. The following Buttons, in addition to other controls, should be available and perform appropriate actions:
Clear - to clear the current inputs and present the default page
Exit - to confirm the exit and then close the application
If you submit an interactive Java application without any GUI controls, you will be given only partial marks.
In order to avoid plagiarism, complete list of classes, fields, methods and GUI layout have not been provided specifically in this assignment so that you are encouraged to develop your own classes appropriately.
