**多线程-线程一打印1,2,3,4,5线程二打印6,7,8,9,10,线程三打印11,12,13,14,15,...知道45结束**

public class Exam3\{  
public static void main(String\[\]args)\{  
MyThread t1=new MyThread("线程一");

MyThread t2=new MyThread("线程二");

MyThread t3=new MyThread("线程三");  
t1.start();  
t2.start();  
t3.start();

\}  
class MyThread extends Thread\{  
static int num=1;  
static Object key="key";  
  
public MyThread(String name) \{  
super(name);  
\}  
public void run() \{  
while(true) \{  
synchronized (key) \{  
if(num<=45)  
for (int i = 0; i < 5; i++) \{  
System.out.println(getName()+":"+ num++);  
\}  
else  
break;  
\}  
try \{  
Thread.sleep(1000);  
\} catch (InterruptedException e) \{  
// TODO Auto-generated catch block  
e.printStackTrace();  
\}  
\}  
  
\}  
\}

**ps:线程执行顺序可能不一样，线程的执行机会是cpu随机分配**
