How to 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
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}
