java - Java 查找数组中最小和第二小的值

Question

我正在尝试创建两种方法，第一种方法用于查找对象数组中的最小值，另一种方法用于查找对象数组中的第二个最小值。

我这样写了两个

public static BanffMarathonRunner getFastestTime(BanffMarathonRunner[] runner){
    if(runner.length == 0){
        return null;
    }
    BanffMarathonRunner fastest = runner[0];
    for(int i = 0; i< runner.length; i++){
        BanffMarathonRunner now = runner[i];
        if(now.Time < fastest.Time){
            fastest = now;

        }
    }
    return fastest;
}
    public static BanffMarathonRunner getSecondFastestTime(BanffMarathonRunner[] runner){
        if(runner.length == 0){
            return null;
        }
        BanffMarathonRunner fastest = runner[0];
        BanffMarathonRunner secondFastest = runner[0];
        for(int i = 0; i< runner.length; i++){
            BanffMarathonRunner now = runner[i];
            if(now.Time < fastest.Time){
                fastest = now;
        for(int j = 0; j< runner.length; j++){
            BanffMarathonRunner now2 = runner[j];
            if(now2.Time < secondFastest.Time){

                secondFastest = now2;
                if(now2.Time == fastest.Time){
                    secondFastest = secondFastest;
                }
            }
        }

            }
        }
        return secondFastest;
    }

我已经弄清楚如何找到最小值，我只需要找到第二小的值，但我不知道如何找到。

有什么想法吗？谢谢!

Answer 1

Arrays.sort(test);
   if(test.length-2 >= 0)
       System.out.println(test[test.length-2]);
