Java LinkedList tutorial with example
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. Operations that index into the list will traverse the list from the beginning or the end, whichever is closer to the specified index.
Example
package com.candidjava.core;
import java.util.LinkedList;
public class LinkedListExample {
public static void main(String[] args) {
LinkedList<String> ll = new LinkedList<String>();
ll.add("hai");
ll.add("123");
ll.add("mathan");
ll.add("lll");
ll.add("mathan");
ll.add("lll");
ll.add("ramya");
ll.add("suji");
ll.add("ravathi");
ll.add("sri");
System.out.println("Linked List .. " + ll);
System.out.println("size ... " + ll.size());
System.out.println("peek ... " + ll.peek());
System.out.println("poll ..." + ll.peekLast());
System.out.println("Linked List .. " + ll);
System.out.println("size ... " + ll.size());
}
}
Output
Linked List .. [hai, 123, mathan, lll, mathan, lll, ramya, suji, ravathi, sri]
size ... 10
peek ... hai
poll ...sri
Linked List .. [hai, 123, mathan, lll, mathan, lll, ramya, suji, ravathi, sri]
size ... 10
