package com.itbuluoge.mythread; class SimpleThread extends Thread { private int priority; public SimpleThread(int i) { priority=i; } public void run() { Thread.currentThread().setPriority(priority); for(int i=0;i<10000;i++) { try { Thread.sleep(100); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } System.out.println(priority); } } } public class PriorityDemo { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub SimpleThread high=new SimpleThread(Thread.MAX_PRIORITY); SimpleThread low=new SimpleThread(Thread.MIN_PRIORITY); high.start(); low.start(); } }
如上述代码所示,运行的两个线程,分别设置最高和最低的优先级,我们可以看看输出结果:
10
1
10
1
10
1
10

可以初步发现,优先级高的,得到的调度会更优先一些,但是也不是非常明显。
