Consider a grade-averaging scheme in which the final average of a student's scores is computed differently
from the traditional average if the student has completed a make-up assignment: drop the lowest score and
compute the new average.
The following table shows several example scores and how they would be average using the scheme
described above.
Student Scores
Make-Up Completed?
Final Average
50, 50, 20, 80, 53
No
(50 + 50 + 20 + 80 + 53)/5.0 = 50.6
30, 80, 85, 87
Yes
(80 + 85+ 87)/3.0 = 84.0
75, 85, 10, 60, 90
Yes
(75 + 85+ 60 + 90)/4.0 = 77.5
Consider the following incomplete StudentRecord class. Each studentRecord object stores a list of that
student's scores and contains methods to compute that student's final average.
public class StudentRecord
private int [] scores; // contains scores.length values
// scores.length > 1
// constructors and other data fields not shown
// returns the average (arithmetic mean)
private double average (int [] scores)
{ /* implementation not shown */}
// returns true if the student has completed a make-up
private boolean makeUpCompleted ()
{ /* implementation not shown */ }
// if the student has completed the make-up, return the
// average of all numbers except the lowest one;
// otherwise, return the average of all numbers
public double finalAverage ()
// your code goes here
Write the studentRecord method finalAyerage (), You MUST call the methods average () and
makeUpCompleted () in the finalAverage () method.
