同学你好，
1、已完成练习，棒棒哒！继续加油！
2、优先级表示重要程度或者紧急程度.但是能不能抢到资源也是不一定，所以这里无法确保先执行哪一个线程
祝学习愉快！

package com.imooc.priority;
class MyThread implements Runnable{
@Override
public void run() {
for(int i=1;i<=10;i++) {
System.out.println("线程"+Thread.currentThread().getName()+"正在运行 "+i);
}
}
}
public class PriorityDemo {
public static void main(String[] args) {
// 获取主线程的优先级
// System.out.println("主线程的优先级："+Thread.currentThread().getPriority());
MyThread mt=new MyThread();
Thread th1=new Thread(mt,"我是线程one");
th1.setPriority(Thread.MAX_PRIORITY);
th1.start();
Thread th2=new Thread(mt,"我是线程two");
th2.setPriority(Thread.MIN_PRIORITY);
th2.start();
/*
* System.out.println("线程one的优先级："+th1.getPriority());
* System.out.println("线程two的优先级："+th1.getPriority());
*/
}
}
老师，设置了优先级也没啥作用，那这个优先级有啥用？0
