package Thread;
public class TestPriority implements Runnable{
    @Override
    public void run() {
        System.out.println(Thread.currentThread().getName()+"-->"+Thread.currentThread().getPriority());
    }
    public static void main(String[] args) {
       TestPriority testPriority = new TestPriority();
        Thread t1 = new Thread(testPriority,"aa");
        t1.setPriority(5);
        Thread t2 = new Thread(testPriority,"bb");
        t2.setPriority(10);
        Thread t3 = new Thread(testPriority,"cc");
        t3.setPriority(1);
        Thread t4 = new Thread(testPriority,"dd");
        t4.setPriority(6);
        t1.start();
        t2.start();
        t3.start();
        t4.start();
