Hi Mohan, welcome to Javaranch.

This particular forum is for Servlets questions. Your question on Threads should be posted in a forum that handles Thread questions, So I am going to move this thread to that forum. Please try to keep your questions on topic to the forum that will best answer your questions.

Good Luck

Mark

The synchronized block of code can only be executed by one thread at a time. Threads not waiting to execute that block are unaffected. So make the synchronzed block as small as possible. For example, if the only data that needs to be thread safe is in an ArrayList, then synchronized block should only contain code that accesses that ArrayList - no more.
