java - Loop several times with different values each time -

i need make loop goes through each time different values rowno. here part of code:

int rowno = 2; file file = new file("path"); workbook workbook = workbook.getworkbook(file); string value = workbook.getsheet(0).getcell(1, rowno).getcontents(); 

the next row numbers 11, 20, 29 , on...

declare array, list, or set rows need check:

int[] rowstocheck = { 11, 20, 29 }; 

and iterate on array taking values:

for (int = 0; < rowstocheck.length; i++) {     string value = workbook.getsheet(0).getcell(1, rowstocheck[i]).getcontents();     system.out.println(value); } 

update:
if numbers consecutive 11 + 9 = 20 + 9 = 29 + 9.... tarik suggested, make counter of loop increment 9.

int numberofrows = // neeed  (int = 0; < numberofrows; i+=9) {     string value = workbook.getsheet(0).getcell(1, i).getcontents();     system.out.println(value); }
