Implementing Producer consumer pattern

Question

I am trying to write a mail utility that places mails in a queue, and it is later consumed by a consumer thread.

I am trying to implement a typical producer-consumer

Answer 1

1. You must use loops so that your producer/consumer code is executed more than once.

2. Your threads do not communicate with each other. Currently you have only two threads being executed. Look at the example in the BlockingQueue javadoc of how to do it.
