New to Java

Hi all,

I was trying to implement pagination in JSP and I came accross a sample code. I tried it on my PC and it worked..

so there were two basic classes at the back of this system and I modified them to suit my need and tried to compile them.. one of them compiled with no hassle but the other will not.

I have all files in the same folder
(
1. pagingData.java
2. Controller.java
3. DataAccess: This class I use for database connection and have no trouble with it)

*** pagingData is instantiated inside Controller.

inside the Controller there is a list and I am trying to add instance of pagingData into it.

*** when I comment out the code for the adding into list the code compiles ok.

Please someone help me with this.

A Million Thanks in advance.

Codes are added below
