线程的优先级(最终还是要看cpu)

package com.Java;

//线程优先级调度
// 注意：不是调整了优先级就一定会被cpu先执行 只是提高了执行概率 一切还是要看cpu调度
public class TestPriority {
    public static void main(String[] args) {
        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);
        Thread t6 = new Thread(myPriority);

        //先设置优先级再启动 main默认是优先的
        t1.setPriority(Thread.MAX_PRIORITY);
        t1.start();

        t2.setPriority(9);
        t2.start();

        t3.setPriority(5);
        t3.start();

        t4.setPriority(1);
        t4.start();

        t5.setPriority(6);
        t5.start();

        t6.setPriority(3);
        t6.start();
    }
}

class MyPriority implements Runnable {

    @Override
    public void run() {
        System.out.println(Thread.currentThread().getName() + "-->" + Thread.currentThread().getPriority());//getPriority 获取线程的优先级常量
    }
}
