JAVA·多线程：线程优先级

每次结果不尽相同，优先级不能完全保证！

package multiThread;
 
public class Thread04Priority {
 
    public static void main(String[] args) {
        // 三个线程
        Thread t1 = new Thread(new MyThread()); // 第一个自定义线程
        Thread t2 = new Thread(new MyThread()); // 第二个自定义线程
        Thread tm = Thread.currentThread(); // 获得当前线程，即主线程
 
        t1.setName("Thread MAX");
        t2.setName("Thread MIN");
        tm.setName("Thread NOR");
 
        // 设置线程的优先级
        t1.setPriority(Thread.MAX_PRIORITY);
        t2.setPriority(Thread.MIN_PRIORITY);
 
        t1.start();
        t2.start();
        Util.printMsg();
    }
}
 
class MyThread implements Runnable {
    public void run() {
        Util.printMsg();
    }
}
 
class Util {
    public static void printMsg() {
        for (int i = 0; i < 200; i++) {
            sleep();
            if (199 == i) {
                Thread thisTread = Thread.currentThread();
                System.out.println();
                System.out.println("当前运行的线程是：" + thisTread);
            }
        }
    }
 
    public static void sleep() {
        try {
            Thread.sleep(10);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}
