学习了这么久，我们来玩个小游戏吧！（ 模拟 游戏的运行）

在多个类中创建的， 方便大家看代码，我把代码全部放到一个里面 

package com.maya.youxi;

public class ZuoZhan {                         //建立父类
    protected String Name;
    protected int GongJiLi;
    protected int HP;
    
    public ZuoZhan(String a,int b,int c){
           this.Name  =a;
        this.GongJiLi =b;
           this.HP    =c;
    }
    
    public void GongJi(){
        
    }
    public void ShouShang(){
        
    }
    public void TaoPao(){
        
    }
    public void DiTaoPao(){
        
    }

}




public class ShiBing extends ZuoZhan {               //士兵类
    
    public ShiBing(String a, int b, int c) {
        super(a,b,c);
    }
    public void GongJi(){
        int x=(int)(Math.random()*1000);
        System.out.println("我方"+this.Name+"攻击敌方坦克,攻击力为"+this.GongJiLi+"，敌方坦克剩余血量"+x);
        if(x<200)
        {
            this.DiTaoPao();
        }
    }
    public void ShouShang(){
            int y=(int)(Math.random()*100);
            if(y<this.GongJiLi+40)
            {
                x+=40;
            }
            
        System.out.println("我方"+this.Name+"受到敌方坦克攻击，坦克攻击力为"+(this.GongJiLi+40)+"士兵受到"+x+"点伤害，剩余血量"+(this.HP-x));
        
        if((this.HP-x)<=20){
            this.TaoPao();
        }
        
    }
    public void TaoPao(){
        System.out.println("我方"+this.Name+"逃跑了");
    }
    public void DiTaoPao(){
        System.out.println("敌方坦克逃跑了");
    }
    
}




public class Tank extends ZuoZhan {                  //坦克类

    public Tank(String a, int b, int c) {
        super(a,b,c);
    }
    public void GongJi(){
        int x=(int)(Math.random()*1000);
        System.out.println("我方"+this.Name+"攻击敌方坦克，攻击力为"+this.GongJiLi+"，敌方坦克剩余血量为"+x);
        if(x<300)
        {
            this.DiTaoPao();
        }
    }
    public void ShouShang(){
        int x=((int)(Math.random()*1000));
        if(x<this.GongJiLi)
        {
            x=x+100;
        }
        System.out.println("我方"+this.Name+"受到敌方坦克攻击，坦克攻击力为"+this.GongJiLi+",我方坦克受到"+x+"点伤害，剩余血量"+(this.HP-x));
        
        if(this.HP-x<200){
            this.TaoPao();
        }
    }
    public void TaoPao(){
        System.out.println("我方坦克逃跑了");
    }
    public void DiTaoPao(){
        System.out.println("敌方坦克逃跑了");
    }

}



public class CaoZong {                 //统一参数
    public void Dong(ZuoZhan z){
        z.GongJi();
        z.ShouShang();

    }

}




public class text {                  //测试
    public static void main (String[] args){
        CaoZong z=new CaoZong();
        ShiBing s=new ShiBing("士兵",10,100);
        Tank    t=new Tank("坦克", 100, 1000);
             　//z.Dong(s);
               z.Dong(t);
        
    }
    
}

　　最后模拟的结果为

 

因为数字为随机数，比如当x和this.HP-x的值少于某个值时，就会触发逃跑方法，高于某个值时，不会触发逃跑方法
