我来给你设计一个Java程序来统计冲刺跑次数,通过模拟两位运动员的冲刺记录，比较谁跑得更多。

简单版（模拟数据）

import java.util.Random;
public class SprintCountCompare {
    // 运动员类
    static class Athlete {
        private String name;
        private int sprintCount;
        private Random random = new Random();
        public Athlete(String name) {
            this.name = name;
            this.sprintCount = 0;
        }
        // 模拟一次训练
        public void train() {
            // 每次训练随机1-5次冲刺
            int sprints = random.nextInt(5) + 1;
            sprintCount += sprints;
            System.out.println(name + " 完成训练，本次冲刺 " + sprints + " 次");
        }
        public int getSprintCount() {
            return sprintCount;
        }
        public String getName() {
            return name;
        }
    }
    public static void main(String[] args) {
        // 创建两位运动员
        Athlete player1 = new Athlete("小明");
        Athlete player2 = new Athlete("小红");
        // 模拟30天训练
        Random random = new Random();
        System.out.println("===== 30天训练记录 =====");
        for (int day = 1; day <= 30; day++) {
            System.out.println("\n第 " + day + " 天训练：");
            player1.train();
            player2.train();
        }
        // 统计数据
        System.out.println("\n===== 最终统计 =====");
        System.out.println(player1.getName() + " 总冲刺次数：" + player1.getSprintCount());
        System.out.println(player2.getName() + " 总冲刺次数：" + player2.getSprintCount());
        // 比较结果
        compareResult(player1, player2);
    }
    // 比较谁更多
    private static void compareResult(Athlete p1, Athlete p2) {
        int diff = p1.getSprintCount() - p2.getSprintCount();
        if (diff > 0) {
            System.out.println("🏆 " + p1.getName() + " 比 " + p2.getName() + " 多跑了 " + diff + " 次");
        } else if (diff < 0) {
            System.out.println("🏆 " + p2.getName() + " 比 " + p1.getName() + " 多跑了 " + Math.abs(diff) + " 次");
        } else {
            System.out.println("🤝 两人冲刺次数相同！");
        }
        // 按百分比统计
        int total = p1.getSprintCount() + p2.getSprintCount();
        double p1Percent = (double) p1.getSprintCount() / total * 100;
        double p2Percent = (double) p2.getSprintCount() / total * 100;
        System.out.printf("%s 占比: %.1f%%%n", p1.getName(), p1Percent);
        System.out.printf("%s 占比: %.1f%%%n", p2.getName(), p2Percent);
    }
}

交互版（用户输入数据）

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
public class SprintCompareInteractive {
    // 运动员数据类
    static class SprintRecord {

            this.athleteName = name;
        }
        public void addSprints(int count) {
            sprintPerDay.add(count);
        }
        public int getTotalSprints() {
            return sprintPerDay.stream().mapToInt(Integer::intValue).sum();
        }
        public int getMaxSprintDay() {
            int max = 0;
            for (int count : sprintPerDay) {
                if (count > max) max = count;
            }
            return max;
        }

        }
