Killing thread after some specified time limit in Java

Make use of ExecutorService to execute the Callable, checkout the methods wherein you can specify the timeout. E.g.

ExecutorService executor = Executors.newSingleThreadExecutor();
executor.invokeAll(Arrays.asList(new Task()), 10, TimeUnit.MINUTES); // Timeout of 10 minutes.
executor.shutdown();

Here Task of course implements Callable.
