Is there any method in java to point the cursor upto 10th record in first page like JDBC methods

>>pageStartIndex=(pageNumbe-1)r*numberOfRecords;

I think you meant what i've given below and i don't think the following could be right

>>
else
endIndex=list.size();
>>

This gives the index

      int listIndex = (pageNumber - 1) * pageSize;

and if you exceed or fall below a possible index, you can wrap:

      listIndex = (listIndex >= 0 && listIndex < numberOfRecords)? listIndex : 0;

Also, bear in mind that using a List may not scale well, so you may like to manipulate your objects without holding them all in memory. A RandomAccessFile may be OK

pageStartIndex=(pageNumbe-1)r*numberOfRecords;
yeah the above is really typo.sorry.

remaining things looks ok ,and i tested .
ie)numberOfRecords= 10;  ---->no of records to be displayed in a page.
if it is constant ,you can keep it java program or u can get it from a properties file.

pageStartIndex=(pageNumber-1)*numberOfRecords;

to check the limit ,that is we should not exceed the existing objects size
this check is for the last page ,3rd page here, which hold only three records .

if(pageStartIndex+numberOfRecords <= list.size())
endIndex=pageStartIndex+numberOfRecords;
else
endIndex=list.size(); // it is the size of the list .
and u can the sublist with
 listObject.sublist(pageStartIndex,endIndex); which will actually give u the list of all elements from pageStartIndex to endIndex-1.


>>A RandomAccessFile may be OK .yeah that's true.if your number of resultant objects is more ,it is not good to keep in memory. we can use random acess file and move the cursor with  RAF.seek.

This is a problem called "pagination" of database results. Here, you have a page in the UI showing 40 rows or more. You want to show only 10 rows at a time with previous and next buttons. There are code snippets available for that, you just have to give the datasource and query and parameters like 10(number of rows in a page)

Common frameworks like Common Controls, strutslogic

In case you are willing to *actually* get the results from db into memory some fwks like
http://struts.application-servers.com/ 

have tags which will directly give you what you want

In case you have the complete list in memory, you just have to write a TLD and a Tag action class, which is the most *non intrusive* of achieving this.

The url i pointed above has some sample code on how to write such tag libraries

vsubram2,

thanks for introducing the new method in List.
