Please help me with this Java coding activity. Thank you.

You should fill in the method getMostImprovedStudent, as well as the method getExamRange. The most improved student is the one with the largest score range.

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

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

Given Code==========================

public class ClassroomTester extends ConsoleProgram { public void run() { 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()); } }

public class Classroom { Student[] students; int numStudentsAdded; public Classroom(int numStudents) { students = new Student[numStudents]; numStudentsAdded = 0; } public Student getMostImprovedStudent() { //input code here } public void addStudent(Student s) { students[numStudentsAdded] = s; numStudentsAdded++; } public void printStudents() { for(int i = 0; i < numStudentsAdded; i++) { System.out.println(students[i]); } } }

public static double nextDouble(){ return Randomizer.getInstance().nextDouble(); }

public static double nextDouble(double min, double max){ return min + (max - min) * Randomizer.nextDouble(); }
