Example of LinkedList in Java

By Arvind Rai, June 09, 2013

java.util.LinkedList is the implementation of List. The main feature of LinkedList is that it allows removing and inserting at end, start and end. LinkedList allows null values for all indexes. LinkedList also implements Deque. Find the example.

LinkedListDemo.java

package com.concretepage.util;
import java.util.LinkedList;
import java.util.List;
public class LinkedListDemo {
    public static void main(String[] args) {
        List<String> lnkList = new LinkedList<String>();
        //add the element at the end
        lnkList.add("A");
        //add the element at the specified index.
        lnkList.add(0,"B");
        //replace the element at the specified index
        lnkList.set(1,"C");

        //get value by index
        System.out.println(lnkList.get(1));

        //iterate LinkedList
        for(String s:lnkList){
            System.out.println(s);
        }
    }
}
