Looking at the javadocs it just says
<T> Future<T> submit(Runnable task, T result)Submits a Runnable task for execution and returns a Future representing that task. The Future's get method will return the given result upon successful completion.
Parameters:
task - the task to submit
result - the result to return
but what does it do with result? does it store anything there? does it just use the type of result to specify the type of Future<T>?
