converting to ScheduledThreadPoolExecutor

Question

I am still a beginner at Java so I have not learned much about threads and concurrency. However, I would like to be able to use the ScheduledThreadPoolExecutor as a timer b

Answer 1

Replace

Timer timer = new Timer();

with

ScheduledExecutorService service = Executors.newSingleThreadScheduledExecutor();

and

class Task extends TimerTask

with

class Task implements Runnable

and

timer.scheduleAtFixedRate(new Task(), 0, 1000);

with

service.scheduleAtFixedRate(new Task(), 0, 1000, TimeUnit.MILLISECONDS);

BTW You should not be attempting to update the GUI on another thread. Instead you have to add a task to the Swing GUI Thread to perform the task

    SwingUtilities.invokeLater(new Runnable() {
        @Override
        public void run() {
            textOut.setText("" + i++);
        }
    });
