run（）方法需要抛出异常
正确程序如下：
public class ThreadTest{
  public static void main(String args[]){
         Thread t1=new MyThread("T1");
         t1.setPriority(Thread.MIN_PRIORITY);
         t1.start();
         Thread t2=new MyThread("T2");
         t2.setPriority(Thread.MAX_PRIORITY);
         t2.start();
         Thread t3=new MyThread("T3");
         t3.setPriority(Thread.MAX_PRIORITY);
         t3.start();
       }//main
}//class ThreadTest
class MyThread extends Thread{
   String message;
   MyThread(String message)
           {
               this.message=message;
            }//MyThread(message)
   public void run()
         {
            try{
                  for(int i=0;i<3;i++)
                  System.out.println(message+" "+getPriority());
               }catch(Exception e){}
         }//run
}//class MyThread

在run方法里面 并不是每次都要用try 和 catch,用到sleep 还有wait()这些方法的时候要用到try chact的 还有你那个run方法是继承来的不能+static变成静态的

Doctor　好厉害！ 问题解决了，结果为： T2 10 T2 10 T2 10 T3 10 T3 10 T3 10 T1 1 T1 1 T1 1

tempnetbar　这个表情什么意思啊？
