execute

void execute(Runnable command,
             long timeout,
             TimeUnit unit)

Executes the given command at some time in the future. The command may execute in a new thread, in a pooled thread, or in the calling thread, at the discretion of the Executor implementation. If no threads are available, it will be added to the work queue. If the work queue is full, the system will wait for the specified time until it throws a RejectedExecutionException

Parameters:

command - the runnable task

timeout - the length of time to wait for the task to complete

unit - the units in which timeout is expressed

Throws:

RejectedExecutionException - if this task cannot be accepted for execution - the queue is full

NullPointerException - if command or unit is null
