Question

I have to translate the following code from Java to Scala:

EDIT: added if-statements in the source (forgot them in first version)

for (Iterator<ExceptionQueuedEvent> i = getUnhandledExceptionQueuedEvents().iterator(); i.hasNext();) 
{
  if (someCondition) {
    ExceptionQueuedEvent event = i.next();
    try {
      //do something
    } finally {
      i.remove();
    }
  }
}

I’m using the JavaConversions library to wrap the Iterable. But as i’m not using the original Iterator, i don’t know how to remove the current element correctly from the collection the same way as i did in Java:

import scala.collection.JavaConversions._
(...)
for (val event <- events) {
  if (someCondition) {
    try {
      // do something
    } finally {
      // how can i remove the current event from events?
      // the underlying type of events is java.lang.Iterable[javax.faces.event.ExceptionQueuedEvent]
    } 
  }
}

Can someone help me?
I guess it’s easy, but i’m still kinda new to Scala and don’t understand what’s going on when Scala wraps something of Java.

Thanks for all the help. So i had to do without using JavaConversions. But it still looks nice&scalafied ;)**

This is my final code, which seems to work:

val eventsIterator = events.iterator    
for (eventsIterator.hasNext) {
  if (someCondition) {
    try {
      // do something
    } finally {
      eventsIterator.remove
    } 
  }
}
