java案例统计角球数哪边领先？

方案1：基础控制台版本
方案2：面向对象版本（更实用）
方案3：带图形化界面版本（Swing GUI）
使用说明

我来为您创建一个Java案例，统计并比较两支球队的角球数,判断哪边领先。

方案1：基础控制台版本

import java.util.Scanner;
public class CornerKickStats {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("=== 角球数统计系统 ===");
        System.out.print("请输入主队名称：");
        String homeTeam = scanner.nextLine();
        System.out.print("请输入客队名称：");
        String awayTeam = scanner.nextLine();
        // 初始化角球数
        int homeCorners = 0;
        int awayCorners = 0;
        while (true) {
            System.out.println("\n当前比分 - 角球数：");
            System.out.println(homeTeam + ": " + homeCorners + " 个角球");
            System.out.println(awayTeam + ": " + awayCorners + " 个角球");
            System.out.print("\n输入：H(主队角球) A(客队角球) Q(退出)：");
            String input = scanner.nextLine().toUpperCase();
            if (input.equals("Q")) {
                break;
            } else if (input.equals("H")) {
                homeCorners++;
            } else if (input.equals("A")) {
                awayCorners++;
            } else {
                System.out.println("无效输入，请输入 H、A 或 Q");
            }
        }
        // 输出最终结果
        System.out.println("\n=== 比赛结束最终统计 ===");
        System.out.println(homeTeam + ": " + homeCorners + " 个角球");
        System.out.println(awayTeam + ": " + awayCorners + " 个角球");
        // 判断哪边领先
        if (homeCorners > awayCorners) {
            System.out.println("🏆 " + homeTeam + " 在角球数上领先！");
        } else if (awayCorners > homeCorners) {
            System.out.println("🏆 " + awayTeam + " 在角球数上领先！");
        } else {

    }
