Why don't you get count at the beginning, store it in a variable and then simple refer to it instead of running query every time you refresh view.

Hey Friends :-) I want to mark this thread solved once im done with this section!

Im close to getting the logic but since i have implemented the following CODE and when i click on the next record it gives me indexoutOfboundexception:

This is the logic implemented:

<%
String Count = request.getParameter("Counter");
int Counter = 0;
if(request.getParameter("Counter") != null) {
  Counter = Integer.parseInt(request.getParameter("Counter"));
}
BorrowerRecordViews Borrower = (BorrowerRecordViews)GetBorrowersRecord.get(Counter);            
%>
<% <%if (Counter>GetBorrowerRecord.size()) {%> 
<a href="ViewStudent.jsp?Counter=<%=Counter+1%>">VIEW NEXT RECORD</a>
 
<%}%>

<% <%if (Counter<GetBorrowerRecord.size()) {%> 
<a href="ViewStudent.jsp?Counter=<%=Counter-1%>">VIEW PREVIOUS RECORD</a>
 
<%}%>

Hey everyone! i tried something new with the code! used the lastIndexof but the problem still comes... IndexOutOfBoundException:

<%
String Count = request.getParameter("Counter");
int Counter = 0;
if(request.getParameter("Counter") != null) {
  Counter = Integer.parseInt(request.getParameter("Counter"));
}
BorrowerRecordViews Borrower = (BorrowerRecordViews)GetBorrowersRecord.get(Counter);            
%>
<% <%if (Counter>GetBorrowerRecord.lastIndexOf)) {%> 
<a href="ViewStudent.jsp?Counter=<%=Counter+1%>">VIEW NEXT RECORD</a>
 
<%}%>
 
<% <%if (Counter<GetBorrowerRecord.lastIndexOf()) {%> 
<a href="ViewStudent.jsp?Counter=<%=Counter-1%>">VIEW PREVIOUS RECORD</a>
 
<%}%>

i USED A different method but the proble still comes any idea why! previously i used size but it still doesnt work!

All help highly appreciated

Don't use random methods. This isn't the lottery. Use logic.
Since you are writing jsps, you know how to loop an array:

for (int i=0;i<array.length;i++) {

Why you set i to be 0 and i<length ? You pass the counter at the request and you use it as argument at the get method.
The list has elements from 0 till size-1, so the counter must be within that range. So display the next, previous links only when the value at the Counter parameter of the links is within that range

            if(request.getParameter("Counter") != null) {
            Counter = Integer.parseInt(request.getParameter("Counter"));
            }
            if (Counter==GetBorrowersRecord.size() || Counter==-1)
                {
                    response.sendRedirect("ViewStudent.jsp");
                }
            else
                {
            BorrowerRecordViews Borrower = (BorrowerRecordViews)GetBorrowersRecord.get(Counter);
