线程-priority（优先级，分配比例）

cpu调用线程是随机分配，通过设置priority，提高线程被cpu代用的比例

 

 

public class priority8  implements  Runnable {
    @Override
    public void run() {
        System.out.println(Thread.currentThread().getName());
    }

    public static void main(String[] args) {

        Thread thread1 = new Thread(new priority8(),"陈1");
        Thread thread2 = new Thread(new priority8(),"陈2");
        Thread thread3 = new Thread(new priority8(),"陈3");
        thread1.setPriority(Thread.MIN_PRIORITY);
        thread2.setPriority(Thread.MAX_PRIORITY);
        thread3.setPriority(Thread.MAX_PRIORITY);
        thread1.start();
        thread2.start();
        thread3.start();
    }
}
