Hi friend,

Code to solve the problem :

import java.util.*;

public class HashTable {

public static void main(String args[]) {
Hashtable table = new Hashtable();

//Put value into the table
table.put("Delhi", "India1");
table.put("Mumbai", "India2");
table.put("Kolkata", "India3");
table.put("Cheenai", "India4");
if(args.length>0)
{
String keyCity = args[0];
if(table.get(keyCity)!=null)
{
System.out.println("Country is :" + table.get(keyCity) );
}
else
{
System.out.println("City Not Found");
}
}
else
{
System.out.println("Please enter City");
}

}
}

Thanks
