java - What is more effective, a huge condition, or a huge array? -

in app, have 2 fragments of each 1 has tridimensional array stores 2160 variables, of 720 it's float , 1440 it's integer.

i have 2 options: 1 - continue huge tridimensional array. 2 - or huge condition.

my concern application's performance on user's mobile phone. consume less time? memory array use high enough affect fragment loading?

notes

• in app, variables it's constant values.
• the user answer series of questions in end display variables.

• there 3 issues:

  1. has 6 options
  2. has 15 options
  3. has 8 options

but have 3 series of questions, in 1 of them display float variables. , in other two, display integer variables.

actually, it's code. results_array[][][] it's big tridimensional array, made part of code, part dealing 720 float values.

switch (rewardselected) {      case 0:           int count = 0;           while (count < 6) {           if(typepack == count) {                int count2 = 0;                while(count2 < 15) {                     if(spinnerselected == count2) {                          int count3 = 0;                          while(count3 < 8) {                               float percent = float.parsefloat(edittextpercent.gettext().tostring());                               float withpercentapplied = (results_array[count][count3][count2] * percent) / 130;                               if(checkfivepercent.ischecked()) {                                    float resultfinal = ((withpercentapplied*5) / 100) + withpercentapplied;                                    textviewresults.get(count3).settext(string.valueof(resultfinal));                               } else {                                    textviewresults.get(count3).settext(string.valueof(withpercentapplied));                               }                               count3++;                          }                     }                     count2++;                }           }           count++;      }           break;      case 1:           break;      case 2:           break; } 

for completeness sake, need.

edit

array contents in json file:

{   "key" : null,   "key1" : null } 

if care constant values/tags. associate real value key
