`default void`	`forEach(Consumer<? super T> action)`	Performs the given action for each element of the `Iterable` until all elements have been processed or the action throws an exception.
`Iterator<T>`	`iterator()`	Returns an iterator over elements of type `T`.
`default Spliterator<T>`	`spliterator()`	Creates a `Spliterator` over the elements described by this `Iterable`.

  - iterator
```
Iterator<T> iterator()
```
    Returns an iterator over elements of type T.
    
    返回:
    
    an Iterator.
  - forEach
```
default void forEach(Consumer<? super T> action)
```
    Performs the given action for each element of the Iterable until all elements have been processed or the action throws an exception. Unless otherwise specified by the implementing class, actions are performed in the order of iteration (if an iteration order is specified). Exceptions thrown by the action are relayed to the caller.
    
    参数:
    
    action - The action to be performed for each element
    
    抛出:
    
    NullPointerException - if the specified action is null

  - spliterator
```
default Spliterator<T> spliterator()
```
    Creates a Spliterator over the elements described by this Iterable.
    
    返回:
    
    a Spliterator over the elements described by this Iterable.
