Question: What is the output of the following program.
1 import java.util.*;
2 class ComparableBird<T> implements Comparable<T> {
3 private int weight;
4 public ComparableBird(int weight) {this.weight = weight;}
5 public int getWeight() {return weight;}
6 @Override
7 public int compareTo(T t) {
8 return this.weight > t.getWeight() ? 1 : (this.weight == t.getWeight() ? 0:-1);
9 }
10 @Override
11 public String toString() {return weight + "";}
12 }
13 public class Birds{
14 public static void main(String args[]) {
15 List<ComparableBird> list = new ArrayList<>();
16 list.add(new ComparableBird(13));list.add(new ComparableBird(9));list.add(new ComparableBird(12));
17 Collections.sort(list);
18 System.out.println(list);
19 }}
Choice:
A. [13, 9, 12]
