Stopping thread with timeout using threadpool

Question

Is there any way to set thread timeout within Executor.newFixedThreadPool ? I have a long queue around 5M which is creating with:
ExecutorService executor = Executors.newFixedThreadPool(500);
total = 10000;
while (totalRows > 0) {
                localStatement.executeQuery("SELECT domainID, domain FROM com WHERE status = '' LIMIT " + total);
                totalRows -= total;
                localResultSet = localStatement.getResultSet();
                while (localResultSet.next()) {
                    HttpGet httpget = new HttpGet("http://" + localResultSet.getString("domain").toLowerCase());
                    executor.submit(new GetThread(httpClient, httpget, localResultSet.getInt("domainID")));
                Thread.sleep(1000);
                while (((ThreadPoolExecutor) executor).getActiveCount() > 10) {
                    try {
                        Thread.sleep(1000);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                localResultSet.close();
                System.out.println("New cycle");
            }But sometimes threads lock and cycle can't finish. Is there anyway to stop thread after N seconds? I can encapsulate Runnable into another Runnable and stop it from there, but it doubles threads, and I believe its not a good way.

Answer 1

yes, you need at least one more thread. you could use one thread to monitor multiple other threads, but you need at least one more thread to wake up after the timeout and check on/cancel the main task.
