Hi Kranthi! welcome to javaranch.

First of all you must change your name as your first name and last name are the same. Please use your actual name..

Secondly I think you are trying to ask about the generic declaration like this

<? extends Number> or <? super Integer>

It is a wildcard generic declaration. I think you must read a tutorial or book to be familiar with it...

kranthi kranthi, please check your private messages. You can see them by clicking My Private Messages.

When you post a question on JavaRanch, please use a meaningful subject line instead of something like "java".

As Henry Wong already told you, your new name unfortunately still does not conform to the naming policy. Your display name should consist of a first and a second name - not just one name. Please change your name again.

<? does not mean the same in Java as in a JSP. Ankit Garg already answered your question above.
