Answer 1

Assuming you have a getRanking() accessor for the private field ranking.

public class ResultComparator implements Comparator {
  public int compare(ResultVoiceObject r1, ResultVoiceObject r2) {
    float f1 = r1.getRanking();
    float f2 = r2.getRanking();
    if(f1 > f2) return 1;
    else if(f1 < f2) return -1;
    return 0;
  }

}

Arrays.sort(resultsArray, new ResultComparator());
