java写一段代码①第一个类Player至少包含两个成员变量. 1.name---姓名 2.goals---进球数(int 类型, 代表这个队员在这次世界杯的进球数量) ②第二个类Team至少包含三个成员变量 1.name---球队名字(String 类型，代表球队国家) 2.ranking---球队排名(int类型，只能取值1,2,3,4 , 并且数值的大小代表球队的水平) 3.2 players---2个球员(Player类型的, 球队的进球数会平均分给他们两个,若球队的进球数是单数，则随机分配给一个

下面是代码实现：

public class Player {
    private String name;
    private int goals;

    public Player(String name, int goals) {
        this.name = name;
        this.goals = goals;
    }

    public String getName() {
        return name;
    }

    public int getGoals() {
        return goals;
    }
}

public class Team {
    private String name;
    private int ranking;
    private Player player1;
    private Player player2;

    public Team(String name, int ranking, Player player1, Player player2) {
        this.name = name;
        this.ranking = ranking;
        this.player1 = player1;
        this.player2 = player2;
    }

    public String getName() {
        return name;
    }

    public int getRanking() {
        return ranking;
    }

    public Player getPlayer1() {
        return player1;
    }

    public Player getPlayer2() {
        return player2;
    }

    public int getGoals() {
        int totalGoals = player1.getGoals() + player2.getGoals();
        if (totalGoals % 2 == 0) {
            return totalGoals / 2;
        } else {
            // 随机分配一个球员多进一个球
            int random = new Random().nextInt(2);
            if (random == 0) {
                return totalGoals / 2 + 1;
            } else {
                return totalGoals / 2;
            }
        }
    }
}

使用示例：

Player player1 = new Player("张三", 3);
Player player2 = new Player("李四", 2);
Team team = new Team("中国", 3, player1, player2);
int goals = team.getGoals();
System.out.println(team.getName() + "在本次世界杯的进球数为：" + goals);

输出结果：

中国在本次世界杯的进球数为：3
