一、线程优先级的管理

package com.yanqi.task18;

public class ThreadPriorityTest extends Thread {
    @Override
    public void run() {
        //System.out.println("子线程的优先级是：" + getPriority()); // 5  10  优先级越高的线程不一定先执行。
        for (int i = 0; i < 20; i++) {
            System.out.println("子线程中：i = " + i);
        }
    }

    public static void main(String[] args) {

        ThreadPriorityTest tpt = new ThreadPriorityTest();
        // 设置子线程的优先级
        tpt.setPriority(Thread.MAX_PRIORITY);
        tpt.start();

        Thread t1 = Thread.currentThread();
        //System.out.println("主线程的优先级是：" + t1.getPriority()); // 5 普通的优先级
        for (int i = 0; i < 20; i++) {
            System.out.println("--主线程中：i = " + i);
        }
    }

}

二、编译打印
