Linked List in java

 

Linked List:-

    A linked list in Java is a linear data structure where elements are stored in nodes. Unlike arrays, which store elements in contiguous memory locations, linked lists use pointers or references to connect nodes, allowing for dynamic memory allocation and efficient insertion and deletion operations

Node:-

    Each element in a linked list is stored in a node. Node Has 2 parts as data and pointer. Data means actual value that store in the list. Pointer is the Points to the next/previous node in the list.

Operations in linked list:-

    There are several operations in java linked list.

1. Insertion - add new node to linked list
2. Deletion  - delete an existing element of the list
3. Search   -  find the specific element

    these are some examples for java linked list operations.

    In java coding, we want to add  library when we coding(import java.util.LinkedList;). Linked List is very easy concept.

Why we need Linked List:-

    linked lists also have drawbacks, such as slower access time for random elements (as compared to arrays), extra memory overhead for storing pointers, and the inability to perform constant-time access based on index. Therefore, the choice between using an array or a linked list depends on the specific requirements and characteristics of the problem at hand.

    It's essential to consider the trade-offs associated with linked lists, such as slower access time for random elements (compared to arrays), extra memory overhead for storing pointers, and the lack of constant-time access based on index. Depending on the specific requirements and characteristics of your application or problem, you may choose between arrays, linked lists, or other data structures that best suit your needs.
