Given the code fragments:
9. class Student {
10. int rollnumber;
11. String name;
12. List courses = new ArrayList();
13. // insert code fragment here
14. public String toString() {
15. return rollnumber + " : " + name + " : " + courses;
16. }
17. }
And,
public class Test {
public static void main (String[] args) {
List cs = new ArrayList();
cs.add("Java");
cs.add("C");
Student s = new Student(123,"Fred",cs);
System.out.println(s);
}
}
Which code fragment, when inserted at line 13, enables class Test to print 123 : Fred : [Java, C] ?
private Student(int i, String name, List cs) {
