How to iterate thru an arraylist and do an action every X times using for loops? Java -


i'm trying iterate thru arraylist of strings made of lines of parsed html. how can use double loop print 0-353, while printing line every 4? help

what must go each line, check see if either world, country, members, or activity. add 4 of data object, every time finish filling object must start new object add array list of objects.

     <a id='slu-world-301' class='server-list__world-link'       href='http://oldschool.runescape.com/game?world=301'>old school 1</a>      <td class='server-list__row-cell server-list__row-cell--country server-list__row-cell--us'>united states</td>      <td class='server-list__row-cell server-list__row-cell--type'>free</td>      <td class='server-list__row-cell'>trade - free</td>      <a id='slu-world-302' class='server-list__world-link' href='http://oldschool.runescape.com/game?world=302'>old school 2</a>      <td class='server-list__row-cell server-list__row-cell--country server-list__row-cell--gb'>united kingdom</td>      <td class='server-list__row-cell server-list__row-cell--type'>members</td>      <td class='server-list__row-cell'>trade - members</td>      <a id='slu-world-303' class='server-list__world-link' href='http://oldschool.runescape.com/game?world=303'>old school 3</a>      <td class='server-list__row-cell server-list__row-cell--country server-list__row-cell--de'>germany</td>      <td class='server-list__row-cell server-list__row-cell--type'>members</td>      <td class='server-list__row-cell'>-</td>

my current code:

        for(int i=1;i<(strs.size() / 4) + 1;i++){             for(int j=0;j<4;j++){                 system.out.println(???? put here ????)             }             system.out.println("-----------------");         }

the reason prints our 0-351 

i<(strs.size() / 4)

since strs.size() = 354 or 353(from comments), outer loop becomes

for(int i=0;i< 88;i++)

and hence achieve max of 87*4 + 3 => 351.

you can change iterate as:

for(int i=0;i<strs.size();i++) {     if(i%4 ==0) {         system.out.println("---------");     }      system.out.println(i); }
