写一段角色扮演游戏java运行代码

以下是一个简单的角色扮演游戏Java代码，它包括一个Player类、一个Enemy类和一个Game类。游戏的目标是让玩家与敌人战斗并获得胜利。

import java.util.Random;

public class Player {
    private String name;
    private int health;
    private int attack;

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

    public String getName() {
        return name;
    }

    public int getHealth() {
        return health;
    }

    public void setHealth(int health) {
        this.health = health;
    }

    public int getAttack() {
        return attack;
    }

    public void attack(Enemy enemy) {
        int damage = this.attack - enemy.getDefense();
        if (damage > 0) {
            enemy.setHealth(enemy.getHealth() - damage);
            System.out.println(this.name + "攻击了" + enemy.getName() + "造成了" + damage + "点伤害！");
            if (enemy.getHealth() <= 0) {
                System.out.println(enemy.getName() + "被" + this.name + "击败了！");
            }
        } else {
            System.out.println(this.name + "攻击了" + enemy.getName() + "但是没有造成伤害...");
        }
    }
}

public class Enemy {
    private String name;
    private int health;
    private int attack;
    private int defense;

    public Enemy(String name, int health, int attack, int defense) {
        this.name = name;
        this.health = health;
        this.attack = attack;
        this.defense = defense;
    }

    public String getName() {
        return name;
    }

    public int getHealth() {
        return health;
    }

    public void setHealth(int health) {
        this.health = health;
    }

    public int getAttack() {
        return attack;
    }

    public int getDefense() {
        return defense;
    }
}

public class Game {
    private Player player;
    private Enemy enemy;

    public Game() {
        player = new Player("玩家", 100, 20);
        enemy = new Enemy("敌人", 50, 10, 5);
    }

    public void start() {
        System.out.println("欢迎来到角色扮演游戏！");
        System.out.println("你的任务是与敌人战斗并获得胜利。");
        System.out.println("开始战斗！");

        Random random = new Random();
        int turn = 1;
        while (player.getHealth() > 0 && enemy.getHealth() > 0) {
            System.out.println("第" + turn + "回合：");
            if (random.nextBoolean()) {
                player.attack(enemy);
            } else {
                enemy.attack(player);
            }
            turn++;
        }

        if (player.getHealth() > 0) {
            System.out.println("恭喜你获得了胜利！");
        } else {
            System.out.println("很遗憾，你失败了...");
        }
    }

    public static void main(String[] args) {
        Game game = new Game();
        game.start();
    }
}

在这个游戏中，玩家和敌人都有名称、健康值和攻击力。玩家可以攻击敌人并造成伤害，而敌人也可以攻击玩家。游戏将一直进行，直到玩家或敌人的健康值降为零。如果玩家胜利，游戏将打印“恭喜你获得了胜利！”；如果玩家失败，游戏将打印“很遗憾，你失败了...”
