How to remove all elements and not just the first Java?

Question

Java

Hello!

I am a complete newbie to Java. Help me please!

There is a code, it removes all selected items

var campaignIterator = AdWordsApp.campaigns()
        .get();
    if (campaignIterator.hasNext()) {
        var campaign = campaignIterator.next();
        var locationIterator = campaign.targeting().targetedLocations().get();

        while (locationIterator.hasNext()) {
            var loc = locationIterator.next();
            loc.remove();
        }
    }

And there is my code, it only removes the first one, how can I repeat the code above?

var campaignMobileAppIterator = campaign.extensions().mobileApps().get();
var campaignMobileApp = campaignMobileAppIterator.next();

campaign.removeMobileApp(campaignMobileApp);

I tried just adding hasNext but something now doesn't delete at all. I can just repeat this script a bunch of times, well, something is not comme il faut.

Good afternoon.
Well hasNext() returns boolean if there is a next element. next() gets the next element.
Accordingly, as in the first example, you first check if there is a next element, and then get it and delete it. Roughly speaking, you need to iterate over the campaignIterator and then remove each element
