How will I know that the data I am getting in a hashtable is numeric or alpha? Please reply ASAP. Thanks.

The data in hashtable is always an object. You cannot store an int there, you have to use the wrapper class Integer, and so on.

Once you retrieve your object, you can try casting it to the different types, like

Object anObject = aHashtable.get(theKey);

if (theKey != null)


    if (anObject instanceof Integer)


// do your logic for Int there, starting from ((Integer)anObject).intValue()



Hope this helps.
