线程的优先级

1. 优先级的范围是1-10，使用getPriority()获取，setPriority()改变

2. main方法的默认优先级是5

3. 优先级的高低值意味着被CPU调度的可能性高低，能否被调度还是CPU，所以不一定优先级高就一定先被调用，只能增加概率

package com.thread.state;
?
public class TestPriority {
    public static void main(String[] args) {
        //主线程默认优先级
        System.out.println(Thread.currentThread().getName()+"->"+Thread.currentThread().getPriority());
?
        MyPriority myPriority = new MyPriority();
?
        Thread t1=new Thread(myPriority);
        Thread t2=new Thread(myPriority);
        Thread t3=new Thread(myPriority);
        Thread t4=new Thread(myPriority);
        Thread t5=new Thread(myPriority);
?
        //先设置优先级再启动
        t1.start();
?
        t2.setPriority(1);
        t2.start();
?
        t3.setPriority(8);
        t3.start();
?
        t4.setPriority(Thread.MAX_PRIORITY);
        t4.start();
?
        t5.setPriority(9);
        t5.start();
    }
?
}
class MyPriority implements Runnable{
?
    @Override
    public void run() {
        System.out.println(Thread.currentThread().getName()+"->"+Thread.currentThread().getPriority());
    }
}
?
