使用其他集合会很容易..但是您也可以使用简单的数组来做到这一点..不仅是第二个，您可以通过对数组进行排序来找到所有运行者的排名..检查此代码..

     public static void main(String args[]) {
        String runners[] = { "Gene", "Elvis", "Presley", "Felicity", "Welcome" };
        int[] timeInMinutes = { 40, 50, 76, 56, 62 };
        int a = 0;
        int tempTime = 0;
        String tempRunner = "";
        for (int i = 0; i < timeInMinutes.length; i++) {
            for (int j = i + 1; j < timeInMinutes.length; j++) {
                if (timeInMinutes[i] > timeInMinutes[j]) {
                    tempTime = timeInMinutes[i];
                    timeInMinutes[i] = timeInMinutes[j];
                    timeInMinutes[j] = tempTime;

                    tempRunner = runners[i];
                    runners[i] = runners[j];
                    runners[j] = tempRunner;
                }
            }
        }
        for (int index = 0; index < runners.length; index++)
            System.out.println("Rank " + (index+1) + ": " + runners[index] + " with " + timeInMinutes[index] + " minutes");
    }
