问题
I am developing contact manager in struts with options(add,delete,modify,print).
I am thinking to map multiple actions(map multiple actions to the same class struts 2.3) to the same class(ContactManager).
I want to know whether it is correct or whether there is need to write separate action for each action?

One good way to go, imho , is to use one Action for every action you have to perform, each one extending its last-forked parent Actions, like:
BaseAction
|
|----------BaseReportAction
| |----- ExcelReportAction
| |----- PDFReportAction
| |----- CSVReportAction
|
|
|----------BaseCRUDAction
| |----- CreateAction
| |----- ReadAction
| |----- UpdateAction
| |----- DeleteAction
|
|
|----------BaseAJAXAction
| |----- ReadSessionCountdownAction
| |----- CheckNewMailsAction
|
etc...
Every Action extended by others will share protected attributes / methods to the children.
Take a look at this: Changing parameters after bind in Struts 2
My 2 cents.

I think you should use a single action. It is totally a good practice, after all they provided the facility to invoke different methods in the same Action class for a purpose! You can achieve something like this by including a wildcard which which can map your action name to appropriate method in Action class.Like this-
<action name="abc*" method="{1}" />
