Java Linked List Tutorial | Edureka
The document explains linked lists as a dynamic data structure where nodes are interconnected and includes elements such as head, nodes, and tail. It distinguishes between different types of linked lists: singly linked lists, doubly linked lists, and circular linked lists, as well as comparing arrays and linked lists in terms of memory consumption, resizing capability, and operation speed. The document also highlights methods in linked lists and their features, emphasizing their synchronization and maintenance of insertion orders.
