实验六 多线程编程 1.随便选择两个城市作为预选旅游目标。实现两个独立的线程分别显示10次城市名，每次显示后休眠一段随机时间(1000ms以内)，哪个先显示完毕，就决定去哪个城市。分别用Runnable接口和Thread类实现。

//继承Thread类

package zuoye;

//继承Thread类
public class City extends Thread{
private String name;
public City(String name) {
super();
this.name = name;
}
public void run() {
for(int i=0;i<10;i++)
{
System.out.println(this.name+i);
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO 自动生成的 catch 块
e.printStackTrace();
}
}
}

}

//Runnable接口

package zuoye;

//Runnable接口
public class City2 implements Runnable {

@Override
public void run() {
	for(int i=0;i<10;i++)
	{
		System.out.println(Thread.currentThread().getName()+" "+i);
	try {
		Thread.sleep(1000);
	} catch (InterruptedException e) {
		// TODO 自动生成的 catch 块
		e.printStackTrace();
	}
	}

}

}

//测试类

package zuoye;

public class Test {

public static void main(String[] args) {
	//Thread类
	
	City c1=new City("铁岭");
	c1.start();
	City c2=new City("纽约");
	c2.start();
	
	//Runnable
	City2 t1=new City2();
	Thread t2=new Thread(t1, "淄博");
	t2.start();
	Thread t3=new Thread(t1, "美国");
	t3.start();

}

}
