Hello Friends,

I need some help. I am working on a project where there is a requirement to perform tasks periodically every 1 sec. I gave a lot thought and read thru lots of articles on the net. I came to one conclusion to use the java.util.concurrent api to solve my problem..

Steps are::
1. Create the tasks
2. Create Worker threads to execute tasks
3. Threads will send process the tasks and publish it to queue.

I need some advise for the third step. should i separate this tasks of publishing to separate thread.

Any good advise will be appreciated.

thanks

I'd imagine that the Executors Framework can be very helpful. All the worker threads share the same executor (which internally has a queue of tasks). Each worker thread submits the task to the executor. The queue, task, and executor are parts of the Executors Framework, so no effort on your side needed

A word of caution: Getting a task to execute reliably every second will be hard. Garbage collection could easily interfere with that.
