This is how I'd do it with a FixedThreadPool, hope it's of some help.

    ExecutorService pool = Executors.newFixedThreadPool(Runtime.getRuntime().availableProcessors());

    List> results = new ArrayList<>();

    for (int i = 0; i < numberOfJobs; i++) {
        MyCallableJob job = new MyCallableJob (...);
        results.add(pool.submit(job));
    }

    for (Future result : results) {
        try { result.get(); }
        catch (InterruptedException | ExecutionException ignorable) { }
    }

    pool.shutdown();
