这代码直接运行和调试后的结果怎么不一样？

 class MyThread extends Thread
{
    public void run()
    {
        for (int i=0;i<10;i++)
        {
            try
            {
                Thread.sleep(100);
            }
            catch (InterruptedException e)
            {
                e.printStackTrace();
            }
            System.out.println("第"+i+"MyThread");
        }
    }
}
public class ThreadTest
{
    public static void main(String[] args)
    {
        MyThread mt=new MyThread();
        mt.start();
        for (int i=0;i<10;i++)
        {
            try
            {
                Thread.sleep(100);
            }
            catch (InterruptedException e)
            {
                e.printStackTrace();
            }
            System.out.println("第"+i+"ThreadTest");
        }
    }
}
