Question

这是一个体育联盟计划，一组团队通过游戏时间表进行比赛并确定获胜者。

程序运行良好，直到最终输出不会让我看到获胜者，而是显示了这一点：

本赛季获得9分的冠军：[Ljava.lang.String; @ e73f9ac

我将其更改为teams.length，这使程序正常工作，但是它会向我显示团队（i）的编号，而不是像“ Vancouver”这样的字符串名称。

谢谢。

    }

    int peak = 0;                                
    int[] total = new int[teams.length];         

    for (int i=0; i<teams.length; i++){                    
      total[i] = 2*wins[i]+ties[i]; 
      if (total[i] > peak) peak = total[i];

      System.out.println(teams[i]+" - " + wins[i] + " wins, " + losses[i] + " losses, " + ties[i] + " ties = " + total[i]);
  }    

  System.out.println("The season winner(s) with " + peak + " points: " + teams);  

  for (int i=0; i<teams.length; i++){
    if (peak < total[i]) peak = total[i];
  }      

}

static int indexOfTeam(String team, String[] teams){  
  for (int i=0; i<teams.length; i++)
    if (team.compareTo(teams[i]) == 0) return i;
    return -1;
  }
}

Answer 1

您将打印teams数组，而不是打印获胜团队。
在除高峰期外迭代商店时，获胜团队的指数：

 int index = -1;
 for (int i=0; i<teams.length; i++){                    
     total[i] = 2*wins[i]+ties[i]; 
     if (total[i] > peak) {
        index = i;
        peak = total[i];
     }
     System.out.println(teams[i]+" - " + wins[i] + " wins, " + losses[i] + " 
   losses, " + ties[i] + " ties = " + total[i]);
 }

最后：

System.out.println("The season winner(s) with " + peak + " points: " + 
 teams[index]);

Answer 2

teams是一个字符串数组，必须在名称后插入索引

Answer 3

如果您要打印所有使用Arrays.toString(teams)的团队，但我认为您只希望打印部分团队数组，因此可以创建获胜者列表

 List<String> winners = new ArrayList<Integer>;
 for (int i=0; i<teams.length; i++){                    
     total[i] = 2*wins[i]+ties[i]; 
     if (total[i] > peak) {
        winners.add(teams[i]);
        peak = total[i];
     }
 System.out.println(teams[i]+" - " + wins[i] + " wins, " + losses[i] + " 
  losses, " + ties[i] + " ties = " + total[i]);
}

可以简单地打印索引对象

System.out.println("The season winner(s) with " + peak + " points: " +winners);

如果您想要一个数组，则可以对获胜者对象使用toArray()。
