如何在锦标赛中获得每队的总积分并获得获胜者

   }

所以，请，我们被困在试图实现每个队的总积分，并根据总积分获得获胜者

Answer 1

我建议将points成员变量从match移动到team。原因是每个队在任何时间点都会有一些积分，所以每个队都有一个积分场是有意义的。

现在您将对这些方法进行以下更改

java团队

public class Team {
   private int points;
   // getters and setters for points

   /* Rest of your class */
}

public void decideResult() {
    if (scoreTeam1 == scoreTeam2) {
        team1.setPoints(team1.getPoints() + 1);
        team2.setPoints(team2.getPoints() + 1);
    } else if (scoreTeam1 > scoreTeam2) {
        team1.setPoints(team1.getPoints() + 2);
    } else {
        team2.setPoints(team2.getPoints() + 2);
    }
}
