//猫大叫一声所有的老鼠开始逃跑主人被惊醒
//要有联动性老鼠和主人的行为是被动的考虑可扩展性猫的叫声可能引起其他的联动效应
namespace _2016._07._18._08
{
public interface Observer
{
void Response();//观察者的反应如是老鼠见到猫的反应
}

public interface Subject
{
void AimAt(Observer obs);！！！！！！！！第一处疑问这里的(Observer obs) 是什么意思
}
//以上是两个接口

public class Mouse:Observer
{
private string name;
public Mouse(string name,Subject subj)！！！！！！1这里的Subject subj 是什么意思
{
this.name = name;
subj.AimAt(this);
}

public void Response()
{
Console.WriteLine(name + "attempt ready to escape!");
}
}

public class Master:Observer
{
public Master(Subject subj)
{
subj.AimAt(this);
}
public void Response()
{
Console.WriteLine("Host waken!");
}

}

public class Cat : Subject
{
private ArrayList observers;
public Cat()
{
this.observers = new ArrayList();
}
public void AimAt(Observer obs)
{
this.observers.Add(obs);
}
public void Cry()
{
Console.WriteLine("Cat Caryed!");
foreach(Observer obs in this.observers)
{
obs.Response();
}
}
}
class Program
{
static void Main(string[] args)
{
Cat cat = new Cat();
Mouse mouse1 = new Mouse("mouse1", cat);
Mouse mouse2 = new Mouse("mouse 2", cat);
Master master = new Master(cat);
cat.Cry();
Console.ReadKey();
//逃跑啥玩意啊就是猫显示叫了然后显示老鼠的名字老鼠逃跑主人醒了。

}
}

}
