java多线程优先级

多线程–优先级

常用方法	描述
setPriority(值)	设置优先级
getPriority(值)	获取优先级

值：

常量	值
NORM_PRIORITY	5 （ 默认）
MIN_PRIORITY	1
MAX_PRIORITY	10

public class YouXianJi {
	public static void main(String[] args) {
		YXJ yxj = new YXJ();
		Thread t1 = new Thread(yxj,"A");
		Thread t2 = new Thread(yxj,"B");
		Thread t3 = new Thread(yxj,"C");
		//设置优先级
		t1.setPriority(Thread.NORM_PRIORITY);
		t2.setPriority(Thread.MIN_PRIORITY);
		t3.setPriority(Thread.MAX_PRIORITY);
		//开启线程
		t1.start();
		t2.start();
		t3.start();
	}
}
class YXJ implements Runnable{
	public void run() {
		System.out.println(Thread.currentThread().getName()+"---执行"+Thread.currentThread().getPriority());
	}
}

注意咯，优先级不是越高执行的概率就越高。（不信？你试试！）
