If you want to know another way to do this try using an ExecutorService

public static void main(String... args) {
    ExecutorService service = Executors.newSingleThreadExecutor();
    for (int i = 0; i < 100; i++) {
        System.out.println("Produced: " + i);

        final int finalI = i;
        service.submit(new Runnable() {
            @Override
            public void run() {
                System.out.println("Consumed: " + finalI);
            }
        });
    }
    service.shutdown();
}

With just 10 tasks the producer can be finished before the consumer starts. If you try 100 tasks you may find them interleaved.
