大数据Java基础第八天作业

第一题：
class Car extends Thread{
private String name;
private Locked lock;
public Car(String name,Locked lock){
this.name = name;
this.lock = lock;
}

public void run(){
synchronized(lock){
System.out.println("车号：" + name + "，开始进入隧道...");
for(int i=1;i<=10;i++){
try{
System.out.println("进入隧道第" + i + "秒");
Thread.sleep(1000*1);
}catch(Exception e){};
}
System.out.println("车号："+ name + "，结束进入隧道...");
}
}
}

class Locked{
//空锁...
}

class CarDemo{
public static void main(String[] args){
Locked lock = new Locked();

Car car001 = new Car("car001",lock);
Car car002 = new Car("car002",lock);
Car car003 = new Car("car003",lock);
Car car004 = new Car("car004",lock);
Car car005 = new Car("car005",lock);

car001.start();
car002.start();
car003.start();
car004.start();
car005.start();
}
}
第二题：
import java.util.ArrayList;
import java.util.List;

class Bee extends Thread{

}catch(Exception e){};
System.out.println("蜜蜂号：" + name + "，生产第" + i + "次蜂蜜！");
list.add(new Integer(i));
i ++;
list.notify();

}
}
}
}
}
