In following example, we will learn how to iterate through elements HashSet object in Java.
Source Code
package com.beginner.examples;
import java.util.HashSet;
import java.util.Iterator;
public class IterateHashSetExample {
public static void main(String[] args) {
// Create a HashSet object
HashSet hSet = new HashSet();
// Add elements
hSet.add("A");
hSet.add("B");
hSet.add("C");
hSet.add("D");
//Get an iterator for this collection
Iterator iterator = hSet.iterator();
System.out.println("All the elements:");
//Iterate through the iterator
while(iterator.hasNext())
{
String element = iterator.next();
System.out.print(element+"t");
}
}
}
Output:
All the elements:
D A B C
