Given:
1. public class Score implements Comparable<Score>{
2.   private int wins, losses;
3.   public Score(int w, int l){wins = w; losses = l;}
4.   public int getWins(){return wins;}
5.   public int getLosses(){return losses;}
6.   public String toString(){
7.     return "<" + wins + "," + losses + ">";
8.   }
9.   //insert code here
10.}

Which method will complete this class?
 A. public int compareTo(Object o){/* more code here */}
 B. public int compareTo(Score other){/* more code here */}
 C. public int compare(Score s1, Score s2){/* more code here */}
 D. public int compare(Object o1, Object o2){/* more code here */}

public interface Comparable<T>
int compareTo(T o)
<T>中為<Score>(第1 行)
compareTo(Score ß
