java_线程优先级

线程优先级分为三个等级:

  MAX_PIORITY:10  优先

  MIN_PRIORITY:1

  NORM_PRIORITY:5  默认

getPriority:获取优先级

setPriority:设置优先级

线程优先级设置只是设置了概率,并不会设置了优先级就能先执行线程

public class TestPriority {
    public static void main(String[] args) {
        A a = new A();
        Thread thread = new Thread(a);
        thread.setPriority(Thread.MAX_PRIORITY);
        thread.start();
        for (int i = 0; i < 50; i++) {
            System.out.println(thread.currentThread().getName()+i);
        }

    }
}

class A implements Runnable{

    @Override
    public void run() {
        for (int i = 0; i < 50; i++) {
            System.out.println(i);
        }
    }
}
