The following example demonstrates how to use the hasMoreElements and nestElement methods of the Enumeration class to traverse and output the contents of the HashTable:
/*

Main.java
*/
import java.util.Enumeration;
import java.util.Hashtable;
public class Main {
public static void main(String[] args) {
Hashtable ht = new Hashtable();
ht.put("1", "One");
ht.put("2", "Two");
ht.put("3", "Three");
Enumeration e = ht.elements();
while(e.hasMoreElements()){
System.out.println(e.nextElement());
}
}
}The output result of running the above code is:
Three Two One
