Data Structures & Algorithms in Java: Doubly & Circular Linked Lists

Skillsoft issued completion badges are earned based on viewing the percentage required or receiving a passing score when assessment is required. Discover how to implement the linked list in Java, including the doubly linked list and the circular linked list, and learn how to perform operations on these linked lists. In this course, you’ll explore variations on the singly linked list that you covered earlier. You’ll see how the doubly linked list holds an additional reference to the previous node in the linked list along with a reference to the next node. This means additional space is required to store each node, but it also makes certain operations faster, such as traversing backwards over the elements in the linked list. You'll also learn about the circular linked list, where the tail of the linked list points back to the head of the linked list.
