Assignment 1: Program StudentMan

1. Requirement <<interface>>
Comparable
Program StudentMan of a flower shop captures and processes
data about an entity named Student and two specific types of
Student named UndergradStudent (undergraduate student) a1_Sid

and PostgradStudent (postgraduate student). Figure 1 shows Student


the concept class diagram of StudentMan. Table 1 lists the
attribute design details of the three classes.
To ease listing of customer objects, program StudentMan UndergradStudent PostgradStudent
requires that Student realises an interface named Comparable.
This interface is provided by Java. The implementation of the
method Comparable.compareTo must compare two Students Figure 1: Class diagram.
by name. Please note that your program will be marked
automatically by a program, which expects you to use
annotation and strictly follow the essential the design rules. An error in one part may affect other parts.

2. Tasks
1. Create a package named a1_Sid as shown in Figure 1, where Sid is your student id. For
example, if your student id is 123456789 then the package name is a1_123456789. You will
need to use this package to hold all the Java classes that you create for the program.
IMPORTANT: Failure to name the package as described will result in an invalid program.

2. Specify and implement class Student with all the essential attribute(s) and operations.
Note: this class must use exceptions where suitable to increase code robustness.
3. Specify and implement class UndergradStudent with all the essential attribute(s) and
operations.
Note: this class must use exceptions where suitable to increase code robustness.
4. Specify and implement class PostgradStudent with all the essential attribute(s) and operations.
Note: this class must use exceptions where suitable to increase code robustness.
IMPORTANT: The essential mutator and observer operations of the same attribute affect one another.
An error in one operation affects the validity of the other operation.

3. Submission
Create a zip-compressed file containing just the folder of the package specified in Task Error:
Reference source not found. You must name the file as follows: a1_Sid.zip, where Sid is your student
id.
Submit your file to the designated submission box for this assignment.

IMPORTANT: Failure to name the file as described above will result in an invalid program. In
particular, ONLY the ZIP format is accepted. Other formats are NOT accepted.
