Java多线程（priority）

本文主要是介绍Java多线程（priority），对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

//测试线程优先级
public class TestPriority {
    public static void main(String[] args) {
        //主线程优先级
        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);
        //先设置优先级
        t1.start();

        t2.setPriority(1);
        t2.start();

        t3.setPriority(4);
        t3.start();

        t4.setPriority(Thread.MAX_PRIORITY);//MAX_PRIORITY=10
        t4.start();

    }
}

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