![]() Otherwise, a newĪrray is allocated with the runtime type of the specified array and ![]() In the specified array, it is returned therein. The returned array is that of the specified array.

Presence of unsynchronized concurrent modification. Note that the fail-fast behavior of an iterator cannot be guaranteedĪs it is, generally speaking, impossible to make any hard guarantees in the Risking arbitrary, non-deterministic behavior at an undetermined Modification, the iterator fails quickly and cleanly, rather than Structurally modified at any time after the iterator is created, inĪny way except through the Iterator's own remove orĪdd methods, the iterator will throw a ConcurrentModificationException. ListIterator methods are fail-fast: if the list is The iterators returned by this class's iterator and List list = Collections.synchronizedList(new LinkedList(.)) This is best done at creation time, to prevent accidental ![]() If no such object exists, the list should be "wrapped" using the That adds or deletes one or more elements merely setting the value ofĪn element is not a structural modification.) This is typicallyĪccomplished by synchronizing on some object that naturally (A structural modification is any operation One of the threads modifies the list structurally, it must be If multiple threads access a linked list concurrently, and at least Note that this implementation is not synchronized. ![]() The beginning or the end, whichever is closer to the specified index. ![]() Operations that index into the list will traverse the list from Implements all optional list operations, and permits allĪll of the operations perform as could be expected for a doubly-linked Here is what the Linked List looks like: is my button code: private void jButtonP1ActionPerformed(-linked list implementation of the List and Deque So the User fills out the Required information and if they want to change profile information such as "Name" or "Gender" they change the information then set the ComboBox next to it to "Yes" then click the button "Save Settings". For some reason my code just doesn't work and I have no idea how to fix it. I need to be able to search a Linked List for certain unique elements (username, password, email) and after finding these elements I need to go to the next node in the list and begin a series of statements allowing users to change profile information. ![]()
