Question

我试图运行一个for循环，在数组列表中打印每个用户分数。但我不知道如何输出最高/最高分的人。有人可以帮助我吗？

for (int i = 0; i < playersList.size(); i++) {

        System.out.println("Player " + (i + 1) + ", "
                + playersList.get(i).getName() + " Score: " + playersList.get(i).getTotalScore());
        playersList.get(i).getFrameScores();


        System.out.println("**************");

    }

Answer 1

首先，在列表中的元素上使用一次迭代找到最大分数。然后，使用另一个迭代来寻找哪些玩家拥有最高分并打印出来。

这是上述算法的伪代码：

int maxScore <- Integer.MIN_VALUE
for each player in playerList
    if maxScore < player->score then
        maxScore <- player->score
    end if
end for
//now you have the max score
for each player in playerList
    if player-> score == maxScore then
        show player info
    end if
end for

Answer 2

试试这个：

double maxScore = playersList.get(0).getTotalScore();
ArrayList<String> maxNames = new ArrayList();
maxNames.add(playersList.get(0).getName());
for (int i = 1; i < playersList.size(); i++) {
    if(playersList.get(i).getTotalScore() > maxScore) {
        maxScore = playersList.get(i).getTotalScore();
        maxNames.clear();
    }
    if(playersList.get(i).getTotalScore() >= maxScore ) {
        maxNames.add(playersList.get(i).getName());
    }
}
StringBuilder names = "";
for(int i=0; i<maxNames.size(); i++) {
    names.append(maxNames.get(i));
    if(i != maxNames.size() - 1) {
        names.append(", ");
    }
}
System.out.println("The player" + (maxNames.size() > 1 ? "s" : "") + " with the highest score " + (maxNames.size() > 1 ? "are" : "is") + " " + names + ", with a score of " + maxScore + ".");

Answer 3

将第一个值指定为max并比较每个值。如果值很大，则将其设置为max并将其与剩余值进行比较。

前者

var max =0;

for(i=o;i<5;i++) {
  if(i==0){ var max = a[i]; }

   if(max < a[i]) {
      max= a[i];
   }
}

alert(max);
