Convert Set of String to Array of String in Java
At first, create a Set of string −
Set<String> setStr = new HashSet<>(Arrays.asList("osCommerce", "PrestaShop", "Magento","Wordpres", "Drupal"));
Now, use the toArray() method to convert to array of string −
String[] arrStr = setStr.toArray(new String[0]);
Example
Following is the program to convert Set of String to Array of String in Java −
import java.util.Arrays; import java.util.Set; import java.util.HashSet; public class Demo { public static void main(String[] args) { Set<String> setStr = new HashSet<>( Arrays.asList("osCommerce", "PrestaShop", "Magento","Wordpres", "Drupal")); System.out.println("Set of String: " + setStr); String[] arrStr = setStr.toArray(new String[0]); System.out.println("Array of String = "+ Arrays.toString(arrStr)); } }
Output
Set of String: [Wordpres, Drupal, PrestaShop, osCommerce, Magento] Array of String = [Wordpres, Drupal, PrestaShop, osCommerce, Magento]
