程序未返回范围和平均值

Question

输出到控制台：

Enter the race times (in seconds):
1 1 4
First place (time in seconds): 1.0
Second place (time in seconds): 1.0
Third place (time in seconds): 4.0
The range of the race times (in seconds): 0.0
The average time of all racers (in seconds): 0.00
Enter another race? (y/n): 

我的代码：

public static void sortTimesAscending(){// Algorithm method that sorts and calculates the whole process (in seconds).
        //Sorting calculation.
        max = Math.max(Math.max(time1, time2), time3);
        min = Math.min(Math.min(time1, time2), time3);
        double mid = time1 + time2 + time3 - max - min;
        //Assigning sorted calculation.
        double firstPlace = min;
        double secondPlace = mid;
        double thirdPlace = max;
        //Calculating range of the race times and the average of the race times of all three racers.
        double range = max - min;
        double average = (time1 + time2 + time3) / 3;
        //Displaying racers' positions.
        System.out.printf("\nFirst place (time in seconds): %4.1f%n", firstPlace);
        System.out.printf("Second place (time in seconds): %4.1f%n", secondPlace);
        System.out.printf("Third place (time in seconds): %4.1f%n", thirdPlace);
        //Determining whether any racers were tied for first or second positions and displaying the rest of the results.
        if (time1 == time2 && time2 == time3){
            System.out.println("\nAll racers shared first place.");
            System.out.printf("The range of race times (in seconds): %4.1f%n", range);
            System.out.printf("The average time of racers (in seconds): %4.1f%n", average);
        }
        else if ((time1 == time2 && time2 > time3) ||
                (time2 == time3 && time2 > time1) ||
                (time1 == time3 && time1 > time2)){
            System.out.println("\nTwo racers shared second place.");
            System.out.printf("The range of race times (in seconds): %4.1f%n", range);
            System.out.printf("The average time of racers (in seconds): %4.1f%n", average);
        }
        else if ((time1 == time2 && time2 < time3) ||
                (time2 == time3 && time2 < time1) ||
                (time1 == time3 && time1 < time1)){
            System.out.println("\nTwo racers shared first place.");
            System.out.printf("The range of race times (in seconds): %4.1f%n", range);
            System.out.printf("The average time of racers (in seconds): %4.1f%n", average);
        }
        else {
            System.out.printf("\nThe range of race times (in seconds): %4.1f%n", range);
            System.out.printf("The average time of racers (in seconds): %4.1f%n", average);
        }
    }

        //getter methods for race times, range, and average

    public double[] getTimes() {
        double[] times = {time1, time2, time3};
        return times;
    }

    public double getRange() {
        return range;
    }

    public double getAvg() {
        return total / 3;
    }

我不知道我的代码有什么问题，它没有将范围和平均值的输出发送到控制台

我尝试了一切，但没有任何效果。请在这种情况下帮助我。

这是代码的修订版本，已解决这些问题：

public class RaceAnalyzer {
    private double time1;
    private double time2;
    private double time3;
    private double max;
    private double min;
    private double range;
    private double total;

    public void setTimes(double t1, double t2, double t3) {
        time1 = t1;
        time2 = t2;
        time3 = t3;
        total = t1 + t2 + t3;
        calculateStatistics();
    }

    private void calculateStatistics() {
        max = Math.max(Math.max(time1, time2), time3);
        min = Math.min(Math.min(time1, time2), time3);
        double mid = total - max - min;

        range = max - min;

        // You can calculate the average here, (if you want)
    }

    public void displayResults() {
        System.out.printf("\nFirst place (time in seconds): %4.1f%n", min);
        System.out.printf("Second place (time in seconds): %4.1f%n", total - max - min);
        System.out.printf("Third place (time in seconds): %4.1f%n", max);

        // Display other results
        System.out.printf("The range of race times (in seconds): %4.1f%n", range);
        System.out.printf("The average time of racers (in seconds): %4.1f%n", total / 3);
    }

    // Your getter methods here

    public static void main(String[] args) {
        RaceAnalyzer analyzer = new RaceAnalyzer();
        analyzer.setTimes(1, 1, 4);
        analyzer.displayResults();
    }
}

在此代码中，我在名为

RaceAnalyzer

的类的方法中组织了计算和显示逻辑。

setTimes()

方法设置比赛时间，然后调用

calculateStatistics()

方法进行计算。

displayResults()

方法显示结果，包括范围和平均值。

main

方法展示了如何使用此类来分析和显示比赛结果。
