How to limit the number of iterations through the List

Question

How I can limit the result of an iterator over my List?

try {
    ArrayList<CalanderQueryOutput> results = new ArrayList<CalanderQueryOutput>();

    List<?> eventsToday = (List<?>) filter.filter(calendar.getComponents(Component.VEVENT));
    CalanderQueryOutput caldavOutput = new CalanderQueryOutput();

    for (Iterator<?> i = eventsToday.iterator(); i.hasNext();) {
    }
    results.add(caldavOutput);
}

I want list only maximum ten results

Answer 1

You can add a counter and break; the loop when the counter reaches a certain value.

Before the loop:

int counter = 1;

in the loop:

if(counter >= 10)
   break;

/* loop code */

counter++;

Answer 2

Just do this:

...
for (Object event : eventsToday.subList(0, Math.min(9, eventsToday.size() - 1))) {
    // do something with "event"
}
...

Answer 3

In the loop , use a counter and check it like this:

if(counter < 10) results.add(caldavOutput);
.....
......
counter++;
