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:
Java
Java
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]);
}
}
// 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:
Program 2:
The LinkedHashSet: [Welcome, To, Geeks, For] The array is: Welcome To Geeks For
// 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]);
}
}
// 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
