Java Program to convert HashSet to Enumeration

Let’s say the following is our HashSet:

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");

Now convert the above HashSet to Enumeration:

Enumeration<String> enumeration = Collections.enumeration(set);

while (enumeration.hasMoreElements())
   System.out.println(enumeration.nextElement());

Example

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());
   }
}

Output

P
Q
R
S
T
U
V
W
X
Z
