Given:
5. class Payload {
6. private int weight;
7. public Payload (int w) { weight = w; }
8. public void setWeight(int w) { weight = w; }
9. public String toString() { return Integer.toString(weight); }
10. }
11. public class TestPayload {
12. static void changePayload(Payload p) { /* insert code */ }
13. public static void main(String[] args) {
14. Payload p = new Payload(200);
15. p.setWeight(1024);
16. changePayload(p);
17. System.out.println(“p is ” + p);
18. } }
Which code fragment, inserted at the end of line 12, produces the output p is 420?
A.
p.setWeight(420);
B.
p.changePayload(420);
C.
p = new Payload(420);
D.
Payload.setWeight(420);
E.
p = Payload.setWeight(420);
