JAVA中的多线程(八)：线程的优先级和yield方法

优先级代表着抢资源的频率

所有线程默认优先级是5

yield()临时释放线程的执行权

class Demo implements Runnable
{
    public void run()
    {
        for(int x = 0; x < 70; x++)
        {
            System.out.println(Thread.currentThread().toString()+"..."+x);
            Thread.yield();
        }
    }
}

class JoinDemo
{
    public static void main(String[] args) throws Exception
    {
        Demo d = new Demo();
        Thread t1 = new Thread(d);
        Thread t2 = new Thread(d);
        t1.start();
        //t1.join();
        //t1.setPriority(Thread.MAX_PRIORITY);
        t2.start();
        for(int x = 0; x < 70; x++)
        {
            //System.out.println("main..."+x);
        }
        System.out.println("over");
    }
}
