The following example demonstrates how to use the iterator() method of the Collection class to traverse the collection:
/*

Main.java
*/import java.util.*;import java.util.*;public class Main {
public static void main(String[] args) {
HashMap< String, String> hMap =
new HashMap< String, String>();
hMap.put("1", "1st");
hMap.put("2", "2nd");
hMap.put("3", "3rd");
Collection cl = hMap.values();
Iterator itr = cl.iterator();
while (itr.hasNext()) {
System.out.println(itr.next());
}
}}The output result of running the above code is:
3rd 2nd 1st
