if I use a for-each loop on a linked list in java,
is it guaranteed that I will iterate on the elements in the order
in which they appear in the list?
Linked list is guaranteed to act in sequential order.
From the documentation
An ordered collection (also known as a sequence). The user of this interface has precise control over where in the list each element is inserted. The user can access elements by their integer index (position in the list), and search for elements in the list.
iterator() Returns an iterator over the elements in this list in proper sequence.
