LinkedList

Get element at specific index of LinkedList example

With this example we are going to demonstrate how to get an element at a specific index of a LinkedList. The LinkedList API provides methods to do such operations. In short, to get an element of a LinkedList, giving an index as parameter you should:

  • Create a new LinkedList.
  • Populate the list with elements, with add(E e) API method of LinkedList.
  • Invoke the get(int index) API method of LinkedList, to return the element at a specific index.

Let’s take a look at the code snippet that follows:
 

package com.javacodegeeks.snippets.core;
 
import java.util.LinkedList;
 
public class GetElementByIndexLinkedList {
 
  public static void main(String[] args) {
 
    // Create a LinkedList and populate it with elements
    LinkedList linkedList = new LinkedList();
    linkedList.add("element_1");
    linkedList.add("element_2");
    linkedList.add("element_3");
    linkedList.add("element_4");
    linkedList.add("element_5");
 

    // Object get(int index) method returns element at specified index from LinkedList
    System.out.println("LinkedList contains : ");
    for(int i=0; i < linkedList.size(); i++)

System.out.println(linkedList.get(i));
 
  }
}

Output:

LinkedList contains : 
element_1
element_2
element_3
element_4
element_5

 
This was an example of how to get an element at a specific index from a LinkedList in Java.
