和毕老师的创建线程代码一样，但是没有老师那种交替抢占CPU资源的效果，为什么...求解（我用的是myeclipse8.5编译的，是不是我这个集成环境有问题呀？）

1. class test extends Thread{
   
2.         public void run(){
   
3.                 for(int i=0; i<60; i++){
   
4.                         System.out.println("test run..."+i);
   
5.                 }
   
6.         }
   
7. }
   
8. 
   
9. public class ThreadDemo {
   
10. 
    
11.         public static void main(String[] args){
    
12.                 test t = new test();
    
13.                 t.start();
    
14.                 for(int i = 0;i < 60; i++){
    
15.                         System.out.println("main run..."+i);
    
16.                 }
    
17.         }
    
18. }

多试几次，换个编译器试试

代码没有问题，你把循环的次数变的大一些。我试了一下，100都不保险，你换成500就成。

谢啦...还真的是这样的原因，看来CPU运行的太快了！

问题已解决！

你的次数太少了~~cpu的运行速度很快的~~你把次数变大~~效果就出来了~~
