线程的优先级

package com.kuang.Demo05;
//测试线程的优先级
public class TestPriority  {
    public static void main(String[] args) {
        System.out.println(Thread.currentThread().getName()+"--->"+Thread.currentThread().getPriority());
        MyPriority myPriority = new MyPriority();
        Thread thread0 = new Thread(myPriority, "0号线程");
        Thread thread1 = new Thread(myPriority, "1号线程");
        Thread thread2 = new Thread(myPriority, "2号线程");
        Thread thread3 = new Thread(myPriority, "3号线程");
        Thread thread4 = new Thread(myPriority, "4号线程");

        thread0.start();

        thread1.setPriority(3);
        thread1.start();

        thread2.setPriority(1);
        thread2.start();

        thread3.setPriority(Thread.MAX_PRIORITY);
        thread3.start();

        thread4.setPriority(8);
        thread4.start();





    }

}

class MyPriority implements Runnable{

    @Override
    public void run() {
        System.out.println(Thread.currentThread().getName()+"--->"+Thread.currentThread().getPriority());
    }
}

优先级设置需要放在start()前面.

性能倒置
