Hi Kristoz
Thank you for your response.
I have tried to figure it out, but no luck.
You mentioned accessing the getter and setter methods and thereafter the
variables of the OwnStudentRecord class through the instance variable
ownStudentRecord created in Student.java.
Can you please give me just one such an example? I have tried many different
options, but cannot figure out what it should look like.
If I use -
ownStudentRecord.getName() {
I get a message that says 'ownStudentRecord package does not exist'
If I try -
public OwnStudentRecord getName(){
return name;
}
The variable 'name' (in the OwnStudentRecord class) cannot be found
If I try -
public OwnStudentRecord getName(){
return ownStudentRecord. ;
the dot operator after ownStudentRecord only gives me access to the getter and
setter methods of the OwnStudentRecord class and not to any of its variables.
Below is my latest attempt, but I still get a 'null' return.
Student.java:
public OwnStudentRecord getOwnStudentRecord() {
return ownStudentRecord;
}
public void setOwnStudentRecord(String name, double mathGrade,
double englishGrade, double scienceGrade) {
this.ownStudentRecord = ownStudentRecord;
}
Main Method:
student1.setOwnStudentRecord("Rene", 60, 70, 80);
System.out.println(
"Student Name = " + student1.getOwnStudentRecord());
Thanks
Kind regards
Rene Erwee

Hi Rene,
The object of the homework is to declare the StudentRecord as an
instance variable, not be a superclass of Student.
Just declare it like any instance variable:
private StudentRecord studentRecord;
Then use its getter and setter methods to access its variables from
within Student.
