Question

If I have 2 database records and 25 records per page, then the following code:

System.out.println("page count: " + (double)2/25);

results in this output:

page count: 0.08

But because I am using this figure for pagination, I need the next highest integer, in this case: 1.

Both Math.ceil and Math.abs produce the result 0 or 0.0.

How do I end up with a page number integer?

Answer 1

The correct way to do that is:

int pages = (totalRecords+recordsPerPage-1)/recordPerPage;

In your case: pages = (2 + 25 – 1)/25 = 26/25 = 1
