LinkedHashSet toArray() method in Java with Example

Last Updated : 24 Dec, 2018

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:

Program 1:

// Java code to illustrate toArray() 
  
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

Program 2:

// Java code to illustrate toArray() 
  
import java.util.*; 
  
public class LinkedHashSetDemo { 
    public static void main(String args[]) 
    { 
        // Creating an empty LinkedHashSet 
        LinkedHashSet<Integer> 
            set = new LinkedHashSet<Integer>(); 
  
        // Use add() method to add 
        // elements into the LinkedHashSet 
        set.add(10); 
        set.add(15); 
        set.add(30); 
        set.add(20); 
        set.add(5); 
        set.add(25); 
  
        // 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: [10, 15, 30, 20, 5, 25]
The array is:
10
15
30
20
5
25
