Just get the key and find out whether both the maps has same value object or different.

What type of object is in the HashMap? A database table isn't a Java type, so it must be something else.

jsp page for displaying purpose, how should i do this.

JPS things should be asked in JSP section, still here is the quick answer:

1. Put the values you want to display on JSP page in request scope.
2. Access them using the EL, JSTL, but never using scriptlet
