Java Program to convert HashSet to Enumeration
<p>Let’s say the following is our HashSet:</p><pre class="result notranslate">HashSet<String> set = new HashSet<String>(); set.add("P"); set.add("Q"); set.add("R"); set.add("S"); set.add("T"); set.add("U"); set.add("V"); set.add("W"); set.add("X"); set.add("Z");</pre><p>Now convert the above HashSet to Enumeration:</p><pre class="result notranslate">Enumeration<String> enumeration = Collections.enumeration(set); while (enumeration.hasMoreElements()) System.out.println(enumeration.nextElement());</pre><h2>Example</h2><pre class="prettyprint notranslate">import java.util.Collections; import java.util.Enumeration; import java.util.HashSet; public class Demo { public static void main(String[] args) { HashSet<String> set = new HashSet<String>(); set.add("P"); set.add("Q"); set.add("R"); set.add("S"); set.add("T"); set.add("U"); set.add("V"); set.add("W"); set.add("X"); set.add("Z"); Enumeration<String> enumeration = Collections.enumeration(set); while (enumeration.hasMoreElements()) System.out.println(enumeration.nextElement()); } }</pre><h2>Output</h2><pre class="result notranslate">P Q R S T U V W X Z</pre>
