In this example, we will write an example to get Enumeration over HashSet with enumeration method of Collections class in Java.
Source Code
package com.beginner.examples;
import java.util.Collections;
import java.util.Enumeration;
import java.util.HashSet;
public class GetEnumerationOverHashSet {
public static void main(String[] args) {
//create HashSet.
HashSet hashSet = new HashSet();
hashSet.add("A");
hashSet.add("B");
hashSet.add("C");
/*
Get Enumeration over Java HashSet object using enumeration(Collection c) method of Collections.
*/
Enumeration enumeration = Collections.enumeration(hashSet);
while(enumeration.hasMoreElements())
System.out.println(enumeration.nextElement());
}
}
Output:
A
B
C
