Add Retrieve Delete Data LinkedList Java Example
Here in this demo you will how to create you own singly linked list and how to add, retrieve and delete data from it.
Little introduction of Linked list: LinkedList is collection of linear data elements which is called nodes where each nodes pointing to next node by pointer. Because each node connected to other node it creates data structure which consists a group of nodes that makes a sequence. All we can say is each nodes will have data and reference to the next node in the sequence. Below is structure:
As you see structure above, it allows very efficient deletion and insertion of the elements from any position in sequence which doing iteration. In below java program we will create our custom linked list with three data insertion and delete one value from it but you could delete add as you needed using below program:
- Now test above custom linked list with below program. LlinkedListTestMain.java:
