I have this code:
for (int j = 0; j < 7; j++) {
if (failureCountAndDUrls.urls.iterator().hasNext()) {
P p2 = new P().appendText("First "+min+" of "+failureCountAndDUrls.count+":");
String id = failureCountAndDUrls.urls.iterator().next();
}
}
urls
is a Set<String>
and yet .next();
returns the same item over and over. Even though there are 7 items
how can iterate all the items correctly?
The problem is you're creating a new iterator every time, and each new iterator has the same initial state.
Reuse the iterator instead.
Iterator<String> it = failureCountAndDUrls.urls.iterator();
for (int j = 0; j < 7; j++) {
if (it.hasNext()) {
P p2 = new P().appendText("First "+min+" of "+failureCountAndDUrls.count+":");
String id = it.next();
}
}
