Is there any way i can retrive the entries from the Hashtable in the sequence that i put them in. Not using the key to get the value, just getting the next element until i reach the end of the Hashtable. The order somehow seems to be different from the order in which i put the data in.

Hashtable doesn't store the order of insertion of its elements. Take a look at Vector or TreeMap instead.

Alternatively, you could extend the class and add in the functionality through the overridden put method.

"Preetham",
The Java Ranch has thousands of visitors every week, many with surprisingly similar names. To avoid confusion we have a naming convention, described at http://www.javaranch.com/name.jsp . We require names to have at least two words, separated by a space, and strongly recommend that you use your full real name. Please log in with a new name which meets the requirements.
Thanks.
