要求主线程执行100次，子线程执行10次，主线程执行100次，子线程执行10次。。。循环

代码如下：

public class Test_02 {

public static void main(String[] args){
    
    MeThread me = new MeThread();
    Thread t = new Thread(me);
    t.start();

    boolean flag = true;
    int i = 1;
    synchronized (me) {
        
        while (flag) {
            System.out.println(Thread.currentThread().getName() + i);
            i++;
            if (i % 100 == 0) {
                try {
                    Thread.currentThread().wait();
                } catch (InterruptedException e) {
                    
                    e.printStackTrace();
                }finally {
                    System.out.println("===========");
                    me.notify();//Thread.currentThread().notifyAll();也不行
                }
            }
        }
    }
}
}

class MeThread implements Runnable {
@Override
public synchronized void run() {
int i = 0;

    boolean flag = true;
    while (flag) {
        System.out.println(Thread.currentThread().getName() + i);
        i++;
        if (i % 10 == 0) {
            try {
                Thread.currentThread().wait();
            } catch (InterruptedException e) {
                
                e.printStackTrace();
            }finally {
                System.out.println("===========");
                
                this.notify();//Thread.currentThread().notifyAll();也不行
            }
        }
    }
}
}
