Bubble popping animation

I think in draw you need nested for loop, to check each bubble against every other bubble:

  for (int indices = 0; indices < bubbles.length-1; indices += 1) {
  for (int indices2 = indices ; indices2 < bubbles.length; indices2 += 1) {
       if (bubbles [indices].together (bubbles [indices2])) {
           bubbles[indices].pops ();
           bubbles[indices2].pops ();
       }
}
}
