Package Summary Overview Summary

### class:Iterator [NONE]
- Type Parameters: `E` - the type of elements returned by this iterator All Known Subinterfaces: ListIterator<E>, PrimitiveIterator<T,T_CONS>, PrimitiveIterator.OfDouble, PrimitiveIterator.OfInt, PrimitiveIterator.OfLong, XMLEventReader All Known Implementing Classes: BeanContextSupport.BCSIterator, EventReaderDelegate, Scanner
      public interface Iterator<E>
An iterator over a collection. `Iterator` takes the place of `Enumeration` in the Java Collections Framework. Iterators differ from enumerations in two ways: Iterators allow the caller to remove elements from the underlying collection during the iteration with well-defined semantics. Method names have been improved. This interface is a member of the Java Collections Framework . Since: 1.2 See Also: `Collection`, `ListIterator`, `Iterable`

### method:hasNext() [NONE]
- #### hasNext
      boolean hasNext()
Returns `true` if the iteration has more elements. (In other words, returns `true` if `next()` would return an element rather than throwing an exception.) Returns: `true` if the iteration has more elements

### method:next() [NONE]
- #### next
      E next()
Returns the next element in the iteration. Returns: the next element in the iteration Throws: `NoSuchElementException` - if the iteration has no more elements

### method:remove() [NONE]
- #### remove
      default void remove()
Removes from the underlying collection the last element returned by this iterator (optional operation). This method can be called only once per call to `next()`. The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method. Implementation Requirements: The default implementation throws an instance of `UnsupportedOperationException` and performs no other action. Throws: `UnsupportedOperationException` - if the `remove` operation is not supported by this iterator `IllegalStateException` - if the `next` method has not yet been called, or the `remove` method has already been called after the last call to the `next` method

### method:forEachRemaining(java.util.function.Consumer) [NONE]
- #### forEachRemaining
      default void forEachRemaining(Consumer<? super E> action)
    Performs the given action for each remaining element until all elements have been processed or the action throws an exception. Actions are performed in the order of iteration, if that order is specified. Exceptions thrown by the action are relayed to the caller. Implementation Requirements: The default implementation behaves as if:
             while (hasNext())
                 action.accept(next());
Parameters: `action` - The action to be performed for each element Throws: `NullPointerException` - if the specified action is null Since: 1.8
