启动十个线程，利用同步方式并发打印线程名字

public class Solution {
    static Object object = new Object();
    public static void main(String[] args) throws Exception{
        for (int i = 0; i < 10; i++) {
            MyThread m = new MyThread();
            Thread t = new Thread(m);
            t.start();
            Thread.sleep(30);
        }
        
    }

    static class MyThread implements Runnable {

        @Override
        public  void run() {
            synchronized(object) {
                System.out.println(Thread.currentThread().getName());
            }
            
        }
    }
}
