    As processors become faster and multiprocessor systems become cheaper, the need to take advantage of multithreading in order to achieve full hardware resource utilization only increases the importance of being able to incorporate concurrency in a wide variety of application categories.

    In this article we are evaluting a new approach to the concurrency. In the last five years computers are becoming even more parallel. Intel is pushing multi-core achiteture also on commodity personal computers. Neverless the computing power is ofter not well used: one again, hardware is a step head of our day-by-day software development. Remember when the 80286 came into light. The 286 was able to provide a multi-programming architecture but without memory management protection. We had to wait 386 hardware to see software working on preemptive multi-tasking, because software cannot cope with unprotected memory. In one word, it costs too much to develop a operating system without the new features the 80386 bring to us. What about concurrent programming? Can we look similarities in the聽 concurrency field?

    Working for two very important Banks, I have the need to play with Closure in Java. I have a lot of trouble looking at a good description of the subject, until I read a post on StackOverflow.

    I have decided to re-cook this subject, adding a my specialized Example also.

    Let’s start!
