In this exercise, complete the method getMostImprovedStudent in the Classroom class, as well as the method getExamRange in the Student class.

The most improved student is the one with the largest exam score range.

To compute the exam score range, you must subtract the minimum exam score from the maximum exam score.

For example, if the exam scores were 90, 75, and 84, the range would be 90 - 75 = 15.

The toString method in the Student class will print the student names with their respective grade levels. Then print who the most improved student was after this.

Sample output:

Ada Lovelace is in grade: 12
Alan Turing is in grade: 11
The most improved student is Ada Lovelace

Code that was given to edit and complete below:

public class ClassroomTester
{
public static void main (String[] args)
{
Classroom c = new Classroom(2);

Student ada = new Student("Ada", "Lovelace", 12);
ada. addExamScore(44);
ada. addExamScore(65);
ada. addExamScore(77);

Student alan = new Student("Alan", "Turing", 11);
alan. addExamScore(38);
alan. addExamScore(24);
alan. addExamScore(31);

// add students to classroom
c. addStudent(ada);
c. addStudent(alan);
c. printStudents();

Student mostImproved = c. getMostImprovedStudent();
System. out. println("The most improved student is " + mostImproved. getName());
}
}
