Question

Rewrite the Course class in Listing 10.6 to implement the comparable and the cloneable
interfaces. The clone method must allow a deep copy on the students field. In addition, add the
equals(Object o) and the toString() methods.
Write a test program to invoke the compareTo, clone, equals, and toString methods in a meaningful way.

Below is the Listing from the book that needs to be rewritten

public class Course {
   private String courseName;
   private String[] students = new String[100];
   private int numberOfStudents;

   public Course(String courseName) {
       this.setCourseName(courseName);
   }

   public void addStudent(String student) {
       students[numberOfStudents] = student;
       numberOfStudents++;
   }

   public String[] getStudents() {
       return students;
   }

   public int getNumberOfStudents() {
       return numberOfStudents;
   }

   public void dropStudent(String student) {
   }

   public String getCourseName() {
       return courseName;
   }
}
