That makes more sense now.

Don't you need to check ? setToPage also checks that to > from
Supposing we start with from=3,to=4
and you want to change it so that from=1,to=2
when you try to change the to page (in the first step) to 3,2
you will also get an IAE.
So you need to examine the existing values to decide which order to do
A bad API design IMO, it should have been setPageRange(int from, int to)
but it is too late for that.
BTW I notice it really is a requirement that from < to and to > from
eg : I see
(toPage != 0 && fromPage > toPage) ||
I would have expected >= ..
.. in fact the docs for setFromPage say :
* @param fromPage an integer greater than zero and less than or
So the implementation looks wrong to me for that and setToPage.
