Hi all,

I've noticed that the elements are not displyed in the order they were added to the table.
Can anybody plz let me know what meight be the reason?
Thanks all,

Hashtable does not maintain the order of objects added to it.
If order is important, use LinkedHashMap

It is its intended behaviour. A Hashtable doesnt guarantee u the order. Read about collections framework in java for more details.
