HashMap Values Iterator Example

In this example, we will write a Java code to iterate over the values of a HashMap using the Iterator interface.

HashMap Values Iterator Example

Here is the Java example to iterate over values of a HashMap:
package com.java.tutorials.collections;

import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;

public class IteratorExample {
 public static void main(String[] args) {
  
  Map<String, String> map = new HashMap<String, String>();
  map.put("key1", "value1");
  map.put("key2", "value2");
  map.put("key3", "value3");
  map.put("key4", "value4");
  
  Iterator<String> iterator = map.values().iterator();
  while (iterator.hasNext()) {
   String value = (String) iterator.next();
   System.out.println(value);
  }
 }
}
Output:
value1
value2
value3
value4
