LinkedHashSet toArray() method in Java with Example

The toArray() method of Java LinkedHashSet is used to form an array of the same elements as that of the LinkedHashSet. Basically, it copies all the element from a LinkedHashSet to a new array.

Syntax:

Object[] arr = LinkedHashSet.toArray()

Parameters: The method does not take any parameters.

Return Value: The method returns an array containing the elements similar to the LinkedHashSet.

Below programs illustrate the LinkedHashSet.toArray() method:

import java.util.*;
  
public class LinkedHashSetDemo {
    public static void main(String args[])
    {
        // Creating an empty LinkedHashSet
        LinkedHashSet<String>
            set = new LinkedHashSet<String>();
  
        // Use add() method to add
        // elements into the LinkedHashSet
        set.add("Welcome");
        set.add("To");
        set.add("Geeks");
        set.add("For");
        set.add("Geeks");
  
        // Displaying the LinkedHashSet
        System.out.println("The LinkedHashSet: "
                           + set);
  
        // Creating the array and using toArray()
        Object[] arr = set.toArray();
  
        System.out.println("The array is:");
        for (int j = 0; j < arr.length; j++)
            System.out.println(arr[j]);
    }
}

Output:


The LinkedHashSet: [Welcome, To, Geeks, For]
The array is:
Welcome
To
Geeks
For

Output:


The LinkedHashSet: [10, 15, 30, 20, 5, 25]
The array is:
