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){

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
