[Solved] How to convert string to boolean condition in java/android?

by


Returning code from server is terrible awful. Anyways, this code I give you do some steps:

  1. removes new lines and multispaces into one length space from input.
  2. finds words by pattern where word starts with if and ends with digits. Adds them to array.
  3. prepares pattern with user chosen options combining into similar to (Q4a.NAOK==\"7\" && Q4b.NAOK==\"5\") (answer 1 and answer2).
  4. checking if array contains word like in point 3. If found, retains word from array and split by comma. Second word from splitting is the answer.
private void doStuff() {
    int answer1 = 2;
    int answer2 = 1;

    String s = "{hidSection=if(((Q4a.NAOK==\"5\" && Q4b.NAOK==\"7\")|| (Q4a.NAOK==\"6\" && Q4b.NAOK==\"6\") || (Q4a.NAOK==\"6\" && Q4b.NAOK==\"7\")|| \n" +
