英文:
How can I give the notification to another thread while both are in infinite loop
问题
我的循环线程正在更新ArrayList中的数据。在ArrayList完成后，我需要向其他线程发送通知，以便其他线程可以将其插入到DB表中。但在记录到DB表时，我的其他线程应该等待。
英文:
My cyclic thread is updating the data in arraylist. After completion of arraylist I need to send notification to other thread so that other thread can insert it into dbtables. But during logging to dbtables my other thread should wait.
