Getting typeof value put in the HashMap

[Jignesh Gohel]

Hi,

How can i get the type of value put in the Hashmap.That is suppose

if i am putting a double value like this:

Double doub = new double("1.5");
hashmap.put("1",doub);


Now in some other class while getting the key's value using hashMap.get("1"), first i want to check the type of the value.

So how can i do that??

Thanks,
Jignesh

As follows:

Object value = hashMap.get("1");
if (value instanceof Double) {
   ....
}

However if you have a design that involves objects of different types as values in a Hashmap, you ought to reconsider that design.
