JAVA - subList returns empty lists inside FOR loop -

i'm facing following issue. have list total (size: s) , need split in n contiguous blocks. here code:

int start_index, end_index;          for(int = 0; < n; i++){             start_index = (s/n)*i;             end_index = start_index + (s/n) - 1;             list<string> subblock = total.sublist(start_index, end_index-1);             system.out.println("block "+i+": "+start_index+" "+end_index);             system.out.println("block "+i+": "+subblock .tostring());         } 

indexes correct: first system.out.println works fine. subblock empty. sublist call outside loop works fine: example, total.sublist(0,2) returns first , second element expected.

is there i'm missing here?

i think made mistake in calculation of start , end index. try following code.

  for(int = 0; < n; i++){         start_index = (s/n)*i;         end_index = start_index + (s/n);         list<string> subblock= (total.sublist(start_index, end_index));           system.out.println("block "+i+": "+start_index+" "+end_index);         system.out.println("block "+i+": "+subblock .tostring());     }
