How to add vector elements to Hashtable

Question

Hi all,
Iam having two variables like name and value.
I choosed a hashtable. I took name as key and value as value.
Now Iam willing to add another variable called order to hashtable.
I want to get both the value and order by name(key).
How can I add this order variable by Vector.
I will be very happy if write the piece of code.
Thanks a lot.
Bye

You retrieve the item from the Map in the same way you did previously.
Vector v = (Vector) myHashTable.get(key);
String value = (String) v.get(0);
String order = (String) v.get(1);
IMO it would be preferable rather than having a vector, you have a class representing the value:
public class MyObject{
  String name;
  String value;
  String order;
}You could then put a MyObject instance into the map rather than using vectors for this.
Also note that while Vectors and Hashtables are not deprecated, there are newer (and better) equivalents in ArrayList and HashMap. You should use those in preference. For maximum flexibility declare any variables as just type List or Map - it doesn't tie you to one specific class.
