LinkedList Object[] toArray() method

This method is available in package java.util.Collection and here, Collection is an interface.
This method is declared in interface Collection and implemented by the LinkedList Class.
This method is used to return a whole array and the array contains all of the element of the linked list.
This method returns an array of objects or elements.

Syntax:

    Object[] toArray(){
    }

Parameter(s):

This method does not accept any parameter but it returns an array of the Linked List.

Return value:

The return type of this method is Object[] that means this method returns an array of all the elements that is represented in the linked list.

Java program to demonstrate example of LinkedList toArray() method

import java.util.LinkedList;

class LinkList {
    public static void main(String[] args) {

        // Create an object of linked list 
        LinkedList list = new LinkedList();

        // use add() method to add few elements in the linked list 
        list.add(10);
        list.add(20);
        list.add(30);
        list.add(40);
        list.add(50);

        //  Current Linked list Output
        System.out.println("The  Current Linked List is :" + list);

        // create an array for objects and copy the linked list to it
        Object[] arr = list.toArray();

        // Traverse the array
        for (int i = 0; i < list.size(); ++i) {
            System.out.println("The element at index " + i + " " + "is :" + arr[i]);
        }
    }
}

Output

D:\Programs>javac LinkList.java

D:\Programs>java LinkList
The  Current Linked List is :[10, 20, 30, 40, 50]
The element at index 0 is :10
The element at index 1 is :20
The element at index 2 is :30
The element at index 3 is :40
The element at index 4 is :50
