Description
Goals
The primary goal of this lab is to write, test and complete a program with multiple classes and
inheritance. You will also code and use constructors, methods and attributes. This program is
an extension of the last lab which adds additional inheritance to your class structure. You will
need to re-use your code from the previous lab as a starting point. This will reinforce the need
for good design and extending an existing code base. For this lab you will also need to create and
efficient design. This is an extension of previous labs with a small change of data. You must change
the previous system to capture all previous data and behavior and add the new data and behavior
specified here.
1. Allows inputs via a simple GUI
2. Instantiates an object from a class you design (class Student or GradStudent) which extends
from another class you already designed (class Person).
3. Stores the data in your Student or GradStudent object
4. Clear the GUI of all data
5. Functions to restore the data from the Student OR GradStudent object to the GUI
6. Add a Java interface called BirthDateCalculate. You will create one method to take the birth
year and calculate the age of any person or student, using this interface, when implemented.
Specifications
The class you create will be a Person class. The Person class will connect to 2 user-defined classes,
Name and Address. The class will contain the following list of data attributes. You must decide
the correct types for each, except the Name and Address types, as they are additional classes.
You must review all of the required attributes of all defined classes and arrive at an efficient,
optimal design that supports inheritance. Then, you must implement that design.
Person class:
• Name (this is a separate class below)
• Address (this is a separate class below)
• Age
• Birth date
Student class:

• Name (this is a separate class below)
• Address (this is a separate class below)
• Major – this must be in a drop down selection from the following majors:
– CIT

– 7-year plan
• Favorite Class – this must be in a drop down selection from the following choices:
– CIT 255
– CIT 155
– Literature of Monty Python
– Presidency of Kanye West

– Theory of killer drones
– no comment
• Age
• Birth date
• Graduation date
• Attended Hogwarts (yes or no)
Name class:
• First Name
• Middle Initial
• Last Name
Address class:
• Address1
• Address2
• City
• State
• ZIP Code (5 digits)

You will also have a child class of Student called GradStudent. Similar to what we have discussed
in class. All of the data in the GUI will be stored in the Student or GradStudent object, not Person.
GradStudent class:
• Thesis Title
• Advisor Name (this is a separate class – reuse Name class)
• Graduation date
• Major – this must be in a drop down selection from the following majors:
– CIT
– Physics
– Math
– Plant Science
– 7-year plan
You must tie the Person, Name and Address Student and GradStudent classes together. You will
need at least 2 user-defined constructors for each class, based on your design.
You will need to create a GUI that can take as input all of these fields, in the reasonably correct
type. Then, you will need to write get and set functions for each of these. These functions will be
the way to message the data between the GUI and the object. On the GUI, there will be three
buttons, with the following actions:
• Save – writes the inputted data to the object
• Clear – deletes all of the data from the GUI
• Restore – retrieves the data from the object and sends it back to the GUI
The successful conclusion to this lab will be the saving and restoring of this data, through your
newly created object.
Submission
Submit the project file(s) to Blackboard by the required date and time. The grading will be done
in lab, but the documents must be submitted to Blackboard as a backup.
