Sandeep,
With all due respect to Mr. Ko Ko Niang, if there's a forum dedicated to a particular topic, we would prefer that you use it. The JavaRanch staff will often move off-topic threads to the forum where they belong, anyway. If no one answers a post after a day or so, it's appropriate to reply to your own post,
in the same thread and add details, clarifications, etc, in the hope of getting an answer.
In the case of your particular query which you sent first to Threads and then to Java in General, Intermediate, less than
one hour elapsed in between your two posts. This suggests that you think it's reasonable to expect that any post you make to JavaRanch will be answered within one hour, and if you haven't gotten an answer in an hour, you need to try something else. That's actually not a reasonable expectation. Questions are sometimes answered within minutes, but often they won't be answered until a few hours or even a few days go by. That's just the way it is. You have to be patient.
