Thank you.
Now I find this constructor redundant.
// Redundant? I cannot pass the average argument here.
StudentRecord annaRecord=new StudentRecord("Anna",90,91,92,0);
double avg=annaRecord.getAverage();
// This would accomplish the same. Use the other constructor.
StudentRecord annaRecord=new StudentRecord("Anna",90,91,92);
double avg=annaRecord.getAverage();
