Timeout a java function when a third party method call hangs

I have a java application which开发者_运维问答 calls a third party method, which can block indefinitely without throwing an exception.

Is it possible to wrap my method call in a timeout block (or thread, or other construct) such that I get back control after I assume the call is never returning?

The ThreadPoolExecutor should do what you need. Using the awaitTermination method:

Blocks until all tasks have completed execution after a shutdown request, or the timeout occurs, or the current thread is interrupted, whichever happens first.

all this multi threading is surely an answer but think if ur application is not a multi-threaded one, you can just store the timestamp of the moment you send the request and check it against the current timestamp. of course you will need a thread to keep track of the time. but all in all you can use that same thread for this purpose for as many functions calls you need. so dont go on implementing the runnable in ur classes. just make one tracker thread.
