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
