Public Method subList

abstract List subList(int fromIndex, int toIndex)

_INSERT_METHOD_SIGNATURE_HERE_

Returns a view of the portion of this list between the specified fromIndex, inclusive, and toIndex, exclusive. If fromIndex and toIndex are equal, the returned list is empty. The returned list is backed by this list, so changes in the returned list are reflected in this list, and vice-versa. The returned list supports all of the optional list operations supported by this list.

This method eliminates the need for explicit range operations (of the sort that commonly exist for arrays). Any operation that expects a list can be used as a range operation by passing a subList view instead of a whole list.

Similar idioms may be constructed for indexOf and lastIndexOf, and all of the algorithms in the Collections class can be applied to a subList. The semantics of this list returned by this method become undefined if the backing list (i.e., this list) is structurally modified in any way other than via the returned list.
