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}
