Web Reference: Doubly-linked list implementation of the List and Deque interfaces. Implements all optional list operations, and permits all elements (including null). All of the operations perform as could be expected for a doubly-linked list. Mar 19, 2026 · LinkedList is a part of the Java Collections Framework and is present in the java.util package. It implements a doubly linked list where elements are stored as nodes containing data and references to the previous and next nodes, rather than in contiguous memory locations. The LinkedList class has the same methods as ArrayList because both follow the List interface. This means you can add, change, remove, or clear elements in a LinkedList just like you would with an ArrayList.
