多线程11：线程的优先级

 1 package com.thread.state;
 2 
 3 //测试线程优先级
 4 public class TestPriority {
 5 
 6     public static void main(String[] args) {
 7 
 8         //主线程默认优先级
 9         System.out.println(Thread.currentThread().getName() + "-->" + Thread.currentThread().getPriority());
10 
11         MyPriority myPriority = new MyPriority();
12 
13         Thread t1 = new Thread(myPriority);
14         Thread t2 = new Thread(myPriority);
15         Thread t3 = new Thread(myPriority);
16         Thread t4 = new Thread(myPriority);
17         Thread t5 = new Thread(myPriority);
18         Thread t6 = new Thread(myPriority);
19 
20         //先设置优先级，再启动
21         t1.start();
22 
23         t2.setPriority(1);
24         t2.start();
25 
26         t3.setPriority(4);
27         t3.start();
28 
29         t4.setPriority(Thread.MAX_PRIORITY);//10
30         t4.start();
31 
32 
33     }
34 }
35 
36 class MyPriority implements Runnable {
37 
38     @Override
39     public void run() {
40         System.out.println(Thread.currentThread().getName() + "-->" + Thread.currentThread().getPriority());
41     }
42 }
43 
44 结果：
45 main-->5
46 Thread-0-->5
47 Thread-1-->1
48 Thread-3-->10
49 Thread-2-->4
