Create and Populate Java Array of Hash Tables

One way to create an array of hash tables is to create Hashtable objects and to assign these to a Hashtable array using curly braces:

Example

Live Demo

import java.util.Hashtable;

public class HashTableOfArrays {
   public static void main(String args[]) {
      Hashtable<String, String> ht1 = new Hashtable();
      ht1.put("Name", "Krishna");
      ht1.put("Age", "28");
      ht1.put("City", "Visakhapatnam");
      ht1.put("Phone", "9848022338");
     
      Hashtable<String, String> ht2 = new Hashtable();
      ht2.put("Name", "Raju");
      ht2.put("Age", "30");
      ht2.put("City", "Chennai");
      ht2.put("Phone", "9848033228");
     
      Hashtable<String, String> ht3 = new Hashtable();
      ht3.put("Name", "Satish");
      ht3.put("Age", "35");
      ht3.put("City", "Hyderabad");
      ht3.put("Phone", "9848023848");
      Hashtable [] hashArray = {ht1, ht2, ht3};
     
      for(int i = 0; i<hashArray.length; i++){
         System.out.println(hashArray[i]);
      }
   }
}

Output

{Name=Krishna, City=Visakhapatnam, Phone=9848022338, Age=28}
{Name=Raju, City=Chennai, Phone=9848033228, Age=30}
{Name=Satish, City=Hyderabad, Phone=9848023848, Age=35}
