Modify the Course class to add a clone method to perform a deep copy on the stud

Question

Modify the Course class to add a clone method to perform a deep copy on the students field. You can use a utility method for performing this deep copy.

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

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

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

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

public int getNumberOfStudents() {
return numberOfStudents;
}

public String getCourseName() {
return courseName;
}

/*******clone method goes here**********/


}

This needs to be done in Java

Explanation / Answer

import java.util.Arrays;

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

   public Course(String courseName, String[] students, int numberOfStudents) {
       super();
       this.courseName = courseName;
       this.students = students;
       this.numberOfStudents = numberOfStudents;
   }

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

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

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

   public int getNumberOfStudents() {
       return numberOfStudents;
   }

   public String getCourseName() {
       return courseName;
   }

   /******* clone method goes here **********/
   public Object clone() throws CloneNotSupportedException {
       Course c = new Course(courseName, Arrays.copyOf(students, 1), numberOfStudents);
       return c;
   }
}
