How To Convert Hashset To Array

import java.util.HashSet;
import java.util.Set;

public class HashSetToArray {

public static void main(String[] args) {

Set<String> hs = new HashSet<String>();
hs.add(“java”);
hs.add(“php”);
hs.add(“html”);
hs.add(“javascript”);
hs.add(“mysql”);

//print hashset
System.out.println(“hashset = “+hs);

String [] arr = new String[hs.size()];

/*
* Returns an array containing all of the
* elements in hs set
*/
hs.toArray(arr);

System.out.println(“Array is “);

for (String str : arr) {
System.out.println(“Element is = “+str);
}

}

}

Output:

hashset = [javascript, php, html, java, mysql]

Array is

Element is = javascript

Element is = php

Element is = html

Element is = java

Element is = mysql
