Java如何设置线程的优先级？

在Java编程中，如何设置线程的优先级？

以下示例如何使用setPriority()方法来设置线程的优先级。

package com.yiibai;

public class SettingPriority { public static void main(String[] args) throws Exception { Thread thread1 = new Thread(); Thread thread2 = new Thread(); Thread thread3 = new Thread(); thread1.setPriority(Thread.MAX_PRIORITY); thread2.setPriority(Thread.NORM_PRIORITY); thread3.setPriority(Thread.MIN_PRIORITY); thread1.start(); thread2.start(); thread3.start(); thread1.join(); thread2.join(); thread3.join(); System.out.println("The priority has been set. Now get priority : "); System.out.println("thread1 priority = " + thread1.getPriority()); System.out.println("thread2 priority = " + thread2.getPriority()); System.out.println("thread3 priority = " + thread3.getPriority()); } } 

Java

上述代码示例将产生以下结果 -

The priority has been set. Now get priority : 
thread1 priority = 10
thread2 priority = 5
thread3 priority = 1
