I'm working on a problem where i have to do pagination of two data lists.
ex. psudo code
int recordsPerPage = 100; // this is dynamic
int currentPage = 1; // this is dynamic
array users = [...]; //length = 55
array admins = [....]; //length = 455
i want pagination like this.
perpage = 100;
user_size = 55;
admin_zise = 455;
total_recors = 510 // 455+55
total_pages = Maths.ceil(total_recors/per_page) //5.1 // 6
50 per entity // 100/2
// records will be sent like this.
page 1> 50 user - 50 admin
page 2> 5 user - 95 admin
page 3> 0 user - 100 admin
page 4> 0 user - 100 admin
page 5> 0 user - 100 admin
page 6> 0 user - 10 admin
I'm not able to figure out logic for this case.
I want to implement this is java (spring boot).
I'm not quite sure what you asking but this might be nearly your question:
@Data
class PaginationResponse {
private List<Object> data;
private int sizePerPage;
private int total;
}
PaginationResponse getResponse(int page, int sizePerPage) {
List<Object> object = new ArrayList<>();
ObjectA[] arr_a = {};
ObjectB[] arr_b = {};
object.addAll(Arrays.asList(arr_a));
object.addAll(Arrays.asList(arr_b));
PaginationResponse response = new PaginationResponse();
int start = (page - 1) * sizePerPage;
response.setData(object.subList(start, start + sizePerPage));
response.setSizePerPage(sizePerPage);
response.setTotal(object.size());
return response;
}
