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.

After making the comparison of two hashmap, i got some results.
For eg. difference between two amount. Now i want to transfer this result to
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
 
It is sorta covered in the JavaRanch Style Guide.
