1.Basic java example program to iterate keys of hashtable
  • Enumeration elements()   This method used to get values of hashmap

  1. package com.iteartekeysHashtable;
  2.  
  3. import java.util.Hashtable;

  4. import java.util.Enumeration;
  5.  
  6. public class HashtableExample{
  7.  
  8. public static void main(String[] args) {
  9.   
  10.  //create Hashtable object
  11.        Hashtable<String,String> hashtable = new Hashtable<String,String>();
  12.        
  13. //add key value pairs to Hashtable
  14. hashtable.put("1","Java Interview Questions");
  15. hashtable.put("2","Java Interview Programs");
  16. hashtable.put("3","Concept and example program");
  17. hashtable.put("4","Concept and interview Questions");
  18. hashtable.put("5","Java Quiz");
  19. hashtable.put("6","Real time examples");
  20.  
  21.  
  22.  
  23. Enumeration e=hashtable.elements();
  24.           
  25.  
  26.            
  27. // display search result
  28.  while (e.hasMoreElements()) {
  29.         System.out.println(e.nextElement());
  30. }    

  31. }
  32.  
  33. }
     



Output:

  1. Real time examples
  2. Java Quiz
  3. Concept and interview Questions
  4. Concept and example program
  5. Java Interview Programs
  6. Java Interview Questions
