Explanation / Answer

/* package codechef; // don't place package name! */

import java.util.*;
import java.lang.*;
import java.io.*;

/* Name of the class has to be "Main" only if the class is public. */
public class Course {
private String courseName;
private String[] students = new String[4];
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;
}
  
public void dropStudent(String student) {
// Left as an exercise in Exercise 10.9
}
}
public class TestCourse {
public static void main(String[] args) {
Course course1 = new Course("Data Structures");
Course course2 = new Course("Database Systems");

course1.addStudent("Peter Jones");
course1.addStudent("Brian Smith");
course1.addStudent("Anne Kennedy");

course2.addStudent("Peter Jones");
course2.addStudent("Steve Smith");

System.out.println("Number of students in course1: "
+ course1.getNumberOfStudents());
String[] students = course1.getStudents();
for (int i = 0; i < course1.getNumberOfStudents(); i++)
System.out.print(students[i] + ", ");
  
System.out.println();
System.out.print("Number of students in course2: "
+ course2.getNumberOfStudents());
String[] students2 = course1.getStudents();
/* for loop for printing students 2 */
for (int i = 0; i < course1.getNumberOfStudents(); i++)
System.out.print(students2[i] + ", ");
}
}
