Question 1

+25−0

In a college, Student s1 chooses a set of courses. Student s2 also chooses all the courses chosen by s1 except the second course, in place of which s2 chooses another course. Write a program that defines two classes Student and Admission. Define a copy constructor to create s2 from s1 such that changing the values of instance variables of either s2 or s1 does not affect the other one. The code takes the name of student s2 and the new course chosen by s2 as input.

Class Student has/should have the following members.
- Private instance variables String name and String[] courses to store the name and the courses chosen, respectively
- Define the required constructor(s)
- Accessor methods getName() and getCourses(int) to get the name of the student and the course at a specific index, respectively.
- Mutator methods setName(String) and setCourses(int, String) to set the name of the student and the course at a specific index, respectively.
Class Admission has method main that does the following.
- Two objects of Student, s1 and s2, are created. s2 is created using s1.
- The name of Student s2 and the second course chosen by s2 are updated by taking the input.
- Finally, the names of s1 and s2 and the second course chosen by s1 and s2 are printed.

    // ***** Define constructor(s) here

    public void setName(String n) {

    public void setCourses(int indx, String c) {
        courses[indx] = c;
    }

    public String getName() {
        return name;
    }

    public String getCourses(int indx) {
        return courses[indx];
    }
}

public class Admission {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        String[] courses = { "Maths", "DL", "DSA", "DC" };
        Student s1 = new Student("Nandu", courses);
        Student s2 = new Student(s1);
        s2.setName(sc.next());
        s2.setCourses(1, sc.next());
        System.out.println(s1.getName() + ": " + s1.getCourses(1));
        System.out.println(s2.getName() + ": " + s2.getCourses(1));
    }
}
