Question

I would like to do an operation every 100ms for 1000ms.

I believe I would need to use the

handler

How do I do that?

Answer 1

Timer t = new Timer();
int count = 0;
t.scheduleAtFixedRate(new TimerTask() {
    count++;
    // Do stuff
    if (count >= 10)
        t.cancel();
}, 0, 100);

This schedules a timer to execute a TimerTask, with a 0 millisecond delay. It will execute the body of the TimerTask every 100 milliseconds. Using count to keep track of where you are in the task, after 10 iterations, you may cancel the timer.

As @Jug6ernaut mentioned, ensure your task won’t take long to execute. Lengthy tasks (ones that take longer than 100 milliseconds, in your case) will cause lag/potentially undesirable results.
