for a coding pattern like
for( Type element : myArrayList ) {
if ( checkSomeCondition(element) == true ) {
myArrayList.remove(element)
}
}
doesn't seem to work, because as the iterator goes on, the current link is
removed.
how do you normally do this simple coding pattern?

the method to use is
to use an explicit iterator,
and do iterator.remove() instead of list.remove(value)
