List<T> foo; Iterator<T> bar = foo.iterator(); T baz = bar.next();
Example:
List<String> fruit = new List {'Orange','Apple','Banana','Peach'};
List<String> seed = new List {'Pip','Seed','Seed','Stone'};
Iterator fruitIterator = fruit.iterator();
Iterator seedIterator = seed.iterator();
while(fruitIterator.hasNext() && seedIterator.hasNext())
{
String fruitItem = fruitIterator.next();
String seedItem = seedIterator.next();
system.debug(fruitItem + seedItem);
}
