Thread: Coding on Object oriented Programming

Help me with my test.I don't know how to start it !

Student
#matricNo: String
#name: String
#course: String
+Student(matricNo: String,
name: String, course: String)
+Display( ):void
UnderGrad
‐CGPA: double
+ UnderGrad (matricNo: String,
name: String, course: String,
CGPA: double)
+Display( ):void
PostGrad
‐ResearchArea: String
+ PostGrad (matricNo: String,
name: String, course: String,
ResearchArea: String)
+Display( ):void
Supervisor
‐StaffID: String
‐SName: String
‐Dept: String
‐svStudent: Arraylist<String>
+ Supervisor (StaffID: String,
SName: String, Dept: String)
+setSvStudents(svStudent:
Arraylist<String>): void
+DispSvStud( ):void

Write a complete program based on the class diagram above. You are required to show
inheritance concept inside your program. Use the following information to produce the code:
‐ Use the constructor for each class to initialize class attributes and accepts parameters sent.
For the subclasses (UnderGrad & PostGrad), they will also initialize its superclass
attributes.
‐ Display() method:
‐ Student class: display all attributes.
‐ UnderGrad class: display all superclass attributes and CGPA.
‐ PostGrad class: display all superclass attributes and Research Area.
- For the Supervisor class, the constructor will be used to initialize the value for attributes
StaffID, SName and Dept. svStudent will store the list of students’ names that are
under the supervisor’s supervision. The value for the svStudent will be assigned using
setSvStudents() method. This method will receive an Arraylist of type String as
parameter. And then this ArrayList will be assigned to the ArrayList svStudent that has
been declared before.
- DispSvStud()method will display the supervisor name and all students under his/her
supervision (the content of the ArrayList).
‐ You are required to write the main() method to implement the classes that have been
defined.
