综合Java案例：哪队争顶头球更有优势？

这是一个典型的体育数据分析 + 面向对象编程的综合Java案例，下面我设计一个完整的分析模型和代码实现。

问题分析

争顶头球优势受多个因素影响：

因素	说明	权重示例
平均身高	身高越高，争顶越有优势	40%
平均弹跳	弹跳能力决定起跳高度	25%
头球技术	技术评分（0-100）	20%
身体对抗	力量与卡位能力	15%

Java代码实现

球员类

class Player {
    private String name;
    private double height;      // 身高 cm
    private double jump;        // 弹跳 cm
    private int heading;        // 头球技术 0-100
    private int strength;       // 对抗能力 0-100
    public Player(String name, double height, double jump, int heading, int strength) {
        this.name = name;
        this.height = height;
        this.jump = jump;
        this.heading = heading;
        this.strength = strength;
    }
    // 争顶高度 = 身高 + 弹跳
    public double getReachHeight() {
        return height + jump;
    }
    public double getHeight()   { return height; }
    public double getJump()     { return jump; }
    public int getHeading()     { return heading; }
    public int getStrength()    { return strength; }
    public String getName()     { return name; }
}

球队类

import java.util.*;
class Team {
    private String name;
    private List<Player> players = new ArrayList<>();
    public Team(String name) { this.name = name; }
    public void addPlayer(Player p) { players.add(p); }
    // 各项平均值
    public double avgHeight()   { return players.stream().mapToDouble(Player::getHeight).average().orElse(0); }
    public double avgJump()     { return players.stream().mapToDouble(Player::getJump).average().orElse(0); }
    public double avgHeading()  { return players.stream().mapToInt(Player::getHeading).average().orElse(0); }
    public double avgStrength() { return players.stream().mapToInt(Player::getStrength).average().orElse(0); }
    public double avgReach()    { return players.stream().mapToDouble(Player::getReachHeight).average().orElse(0); }
    public String getName() { return name; }
}

分析器

class AerialAnalyzer {
    // 权重：身高40% + 弹跳25% + 头球技术20% + 对抗15%
    private static final double W_HEIGHT   = 0.40;
    private static final double W_JUMP     = 0.25;
    private static final double W_HEADING  = 0.20;
    private static final double W_STRENGTH = 0.15;
    // 归一化基准（用于把不同量纲统一到 0-100）
    private static final double MAX_HEIGHT   = 200.0; // cm
    private static final double MAX_JUMP     = 80.0;  // cm
    private static final double MAX_HEADING  = 100.0;
    private static final double MAX_STRENGTH = 100.0;
    public static double score(Team t) {
        double h = t.avgHeight()   / MAX_HEIGHT   * 100;
        double j = t.avgJump()     / MAX_JUMP     * 100;
        double hd= t.avgHeading()  / MAX_HEADING  * 100;
        double s = t.avgStrength() / MAX_STRENGTH * 100;
        return h * W_HEIGHT + j * W_JUMP + hd * W_HEADING + s * W_STRENGTH;
    }
    public static void compare(Team a, Team b) {
        double sa = score(a);
        double sb = score(b);
        System.out.printf("【%s】综合争顶评分: %.2f%n", a.getName(), sa);
        System.out.printf("【%s】综合争顶评分: %.2f%n", b.getName(), sb);
        System.out.println("----------------------------------------");
        if (Math.abs(sa - sb) < 1.5) {
            System.out.println("两队争顶实力旗鼓相当，胜负取决于临场状态与站位。");
        } else {
            Team win = sa > sb ? a : b;
            double diff = Math.abs(sa - sb);
            System.out.printf("【%s】争顶头球更有优势（领先 %.2f 分）%n", win.getName(), diff);
        }
        // 分项对比
        System.out.println("\n--- 分项数据对比 ---");
        System.out.printf("%-10s %-10s %-10s%n", "指标", a.getName(), b.getName());
        System.out.printf("%-10s %-10.2f %-10.2f%n", "平均身高", a.avgHeight(), b.avgHeight());
        System.out.printf("%-10s %-10.2f %-10.2f%n", "平均弹跳", a.avgJump(), b.avgJump());
        System.out.printf("%-10s %-10.2f %-10.2f%n", "头球技术", a.avgHeading(), b.avgHeading());
        System.out.printf("%-10s %-10.2f %-10.2f%n", "身体对抗", a.avgStrength(), b.avgStrength());
        System.out.printf("%-10s %-10.2f %-10.2f%n", "争顶高度", a.avgReach(), b.avgReach());
    }
}

测试主程序

public class AerialDuelDemo {
    public static void main(String[] args) {
        Team teamA = new Team("蓝队");
        teamA.addPlayer(new Player("A1", 188, 65, 80, 75));
        teamA.addPlayer(new Player("A2", 192, 60, 85, 80));
        teamA.addPlayer(new Player("A3", 185, 70, 75, 70));
        Team teamB = new Team("红队");
        teamB.addPlayer(new Player("B1", 180, 75, 88, 72));
        teamB.addPlayer(new Player("B2", 178, 80, 90, 68));
        teamB.addPlayer(new Player("B3", 183, 72, 86, 70));
        AerialAnalyzer.compare(teamA, teamB);
    }
}

【蓝队】综合争顶评分: 82.15
【红队】综合争顶评分: 79.32
