Collections.sort(transactions, new Comparator<Transaction>(){
  public int compare(Transaction t1, Transaction t2){
    return t1.getValue().compareTo(t2.getValue());
  }
});

public class ForkJoinCalculator extends RecursiveTask<Double> {

   public static final long THRESHOLD = 1_000_000;

   private final SequentialCalculator sequentialCalculator;
   private final double[] numbers;
   private final int start;
   private final int end;

   public ForkJoinCalculator(double[] numbers, SequentialCalculator sequentialCalculator) {
     this(numbers, 0, numbers.length, sequentialCalculator);
   }
