简单的回合制小游戏

设计需求：

（1）怪物的共有的属性有：名称、血量、攻击力、防御力；共有的方法有：显示属性、判定是否死亡、和攻击

（2）设置两种怪物：独眼巨人，树怪

（3）独眼巨人特有的属性有：武器（狼牙棒或钉锤）；独眼巨人具有的攻击方法是：使用武器（狼牙棒或钉锤）攻击

（4）树怪特有的属性：高度；树怪的攻击方式是使用树枝缠绕攻击

（5）创建2只独眼巨人和1只树怪的对象，放入集合中，并轮流攻击集合中的下一个对象（0攻击1,1攻击2,2攻击0），直到只剩下一只怪物存活

（6）伤害值计算公式为：攻击者攻击力-被攻击者防御力，被攻击者的血量会要扣减调伤害值

（7）死亡判定规则为：血量小于等于0

怪兽父类：

public class Monster {
	public String name;
	public int hp;
	public int power;
	public int defence;
	public boolean live = true;
	public Monster(String name, int hp, int power, int defence) {
		super();
		this.name = name;
		this.hp = hp;
		this.power = power;
		this.defence = defence;
	}
	public void show() {
		System.out.println("怪物名称："+name);
		System.out.println("血量："+hp);
		System.out.println("攻击力："+power);
		System.out.println("防御力："+defence);
	}
	public void attacMode(Monster monster) {
		
	}
}

　独眼巨人类：

public class Monser1 extends Monster{
	String arm;
	
	public Monser1(String name, int hp, int power, int defence,String arm) {
		super(name, hp, power, defence);
		this.arm = arm;
	}
	
	public void attacMode(Monster monster) {
		monster.hp  = monster.hp - (this.power-monster.defence);
		if(monster.hp>0) {
			System.out.println(this.name+"使用"+this.arm+"进行攻击，对"+monster.name+"造成"
					+(this.power-monster.defence)+"点伤害");
		}
		else {
			monster.hp = 0;
			System.out.println(monster.name+"死亡");
			monster.live = false;
		}
	}
	public void show() {
		System.out.print("怪物名称："+name);
		System.out.print("  血量："+hp);
		System.out.print("  攻击力："+power);
		System.out.print("  防御力："+defence);
		System.out.println("  武器："+arm);
	}
}

树精类：

public class Monser2 extends Monster{

	String Height;
	public Monser2(String name, int hp, int power, int defence,String Height) {
		super(name, hp, power, defence);
		this.Height = Height;
	}
	
	public void attacMode(Monster monster) {
		monster.hp  = monster.hp - (this.power-monster.defence);
		if(monster.hp>0) {
			System.out.println(this.name+"使用树枝缠绕进行攻击，对"+monster.name+"造成"
					+(this.power-monster.defence)+"点伤害");
		}
		else {
			monster.hp = 0;
			System.out.println(monster.name+"死亡");
			monster.live = false;
		}
	}
	
	public void show() {
		System.out.print("怪物名称："+name);
		System.out.print("  血量："+hp);
		System.out.print("  攻击力："+power);
		System.out.print("  防御力："+defence);
		System.out.println("  高度："+Height);
	}

}

测试类：

import java.util.ArrayList;
import java.util.List;

public class Demo {

	public static void main(String[] args) {
		Monser1 kt = new Monser1("独眼巨人凯特",100,25,10,"钉锤");
		Monser1 km = new Monser1("独眼巨人卡姆",100,30,7,"狼牙棒");
		Monser2 gy = new Monser2("树怪盖亚",80,35,12,"10.5");
		List<Monster> list = new ArrayList<Monster>();
		list.add(kt);
		list.add(km);
		list.add(gy);
		for(int i=0;i<list.size();i++) {
			list.get(i).show();
		}
		int size = 0;
		while(true) {
			if(list.size()==1) {
				System.out.println(list.get(0).name+"获得胜利");
				break;
			}
			if(size<list.size()) {
				list.get(size).attacMode(list.get(size+1));
				if(list.get(size+1).hp==0)
					list.remove(size+1);
				size++;
			}
			if(size==list.size()-1) {
				list.get(size).attacMode(list.get(0));
				if(list.get(0).hp==0)
					list.remove(0);
				size = 0;
			}
		}
	}
