Java配列：スコアをソートして適切な名前で表示する

Question

この配列を対応する名前で最高から最低まで並べ替えることができます。配列のスコアを最低から最高まで短くする方法を作ったが、一緒にプリントアウトするために名前とスコアを結びつける方法を見つけるのが難しい。 は、あなたがオブジェクトを含む、二つの平行アレイを使用して、代わりに単一のものを使用しているという問題がある

Answer 1

（私はこれと同じ理由のための私の方法と呼ばれていません）。

は、nameとscoreフィールドで、クラスPlayerを作成Playerの配列を作成し、そのスコア（Comparator<Player>を使用）で選手を並べ替えます。

Answer 2

あなたがより良いクラスを使用してデータを記述：

public class Player { 
    private String name; 
    private int score; 

    public Player(String name, int score) { 
     this.name = name; 
     this.score = score; 
    } 

    public String getName() { 
     return name; 
    } 
    public void setName(String name) { 
     this.name = name; 
    } 
    public int getScore() { 
     return score; 
    } 
    public void setScore(int score) { 
     this.score = score; 
    } 
} 

そしてComparator<Player>を使用してPlayer[]内の要素を並べ替える：

class ByScoreComparator implements Comparator<Player> { 
    @Override public int compare(Player p1, Player p2) { 
     return Integer.compare(p1.getScore(), p2.getScore()); 
    } 
} 

// ... 

Arrays.sort(players, new ByScoreComparator());
