afplib has some sample code to do this. Basically you need to iterate over all structured fields in your AFP and count the number of BPG (Begin Page). This snippet is taken from here:

try (AfpInputStream in = new AfpInputStream(
                new BufferedInputStream(new FileInputStream(s)))) {

            int pages = 0;
            int resources = 0;

            SF sf;
            while((sf = in.readStructuredField()) != null) {
                log.trace("{}", sf);

                switch(sf.getId()) {
                case SFName.BPG_VALUE:
                    pages++;
                    if(progress && pages % 1000 == 0)
                        System.out.print(String.format("\r%06d %04d %s", pages, resources, s));
                    break;
                case SFName.BRS_VALUE:
                    resources++;
                    if(progress && resources % 1000 == 0)
                        System.out.print(String.format("\r%06d %04d %s", pages, resources, s));
                    break;
                }
            }

            if(progress)
                System.out.print("\r");
            System.out.println(String.format("%06d %04d %s", pages, resources, s));

        } catch (Exception e) {
        }
