How to convert LinkedList to Array in Java?

Given a Linked List in Java, the task is to convert this LinkedList to Array.


Input: LinkedList: ['G', 'e', 'e', 'k', 's'] 
Output: Array: ['G', 'e', 'e', 'k', 's'] 

Input: LinkedList: [1, 2, 3, 4, 5]
Output: Array: [1, 2, 3, 4, 5] 


  1. Get the LinkedList
  2. Convert the LinkedList to Object array using toArray() method.
  3. Convert the Object array to desired type array using Arrays.copyOf() method.
  4. Return the print the Array

Below is the implementation of the above approach:





// Java program to convert
// LinkedList to Array
import java.util.*;
public class GFG {
    // Function to convert LinkedList to Array
    public static <T> Object[] convertLinkedListToArray(LinkedList<T> linkedList)
        // Converting LinkedList to Array
        Object[] array = linkedList.toArray();
        return array;
    public static void main(String args[])
        // Creating linked list
            linkedList = new LinkedList<String>();
        // Adding elements to the linked list
        // Print the LinkedList
        System.out.println("Linked list: "
                           + linkedList);
        // Converting LinkedList to Object Array
        Object[] objArray = convertLinkedListToArray(linkedList);
        // Convert Object[] to String[]
        String[] array = Arrays.copyOf(objArray,
        // Print the String Array
        System.out.println("Array: "
                           + Arrays.toString(array));



Linked list: [G, e, e, k, s]
Array: [G, e, e, k, s]
