### Question:
MelodicGenerator { public Integer extractMeanfromAccents(RhythmicAccents rhythmicAccents) { Integer total = Integer.parseInt(rhythmicAccents.getOneOne()); total = total + Integer.parseInt(rhythmicAccents.getOneTwo()); total = total + Integer.parseInt(rhythmicAccents.getOneThree()); total = total + Integer.parseInt(rhythmicAccents.getOneFour()); total = total + Integer.parseInt(rhythmicAccents.getTwoOne()); total = total + Integer.parseInt(rhythmicAccents.getTwoTwo()); total = total + Integer.parseInt(rhythmicAccents.getTwoThree()); total = total + Integer.parseInt(rhythmicAccents.getTwoFour()); total = total + Integer.parseInt(rhythmicAccents.getThreeOne()); total = total + Integer.parseInt(rhythmicAccents.getThreeTwo()); total = total + Integer.parseInt(rhythmicAccents.getThreeThree()); total = total + Integer.parseInt(rhythmicAccents.getThreeFour()); total = total + Integer.parseInt(rhythmicAccents.getFourOne()); total = total + Integer.parseInt(rhythmicAccents.getFourTwo()); total = total + Integer.parseInt(rhythmicAccents.getFourThree()); total = total + Integer.parseInt(rhythmicAccents.getFourFour()); return total / 16; }  QueueState setMelodicPositions(QueueState queueState); RhythmicAccents getHarmonicLoopAltBarAccents(ProgressionUnitBar pBar, int barPosition); RhythmicAccents getHarmonicLoopBarAccents(ProgressionUnitBar pBar, int barPosition); RhythmicAccents getBeatLoopAltBarAccents(ProgressionUnitBar pBar, int barPosition); RhythmicAccents getBeatLoopBarAccents(ProgressionUnitBar pBar, int barPosition); RhythmicAccents sumRhythmicAccents(List<RhythmicAccents> accents); RhythmicAccents setAccentsAboveMean(RhythmicAccents rhythmicAccents, int mean); Integer extractMeanfromAccents(RhythmicAccents rhythmicAccents); Map<ProgressionType, List<HarmonyExtraction>> createTypeToExtractionMap(QueueState queueState);  }### Answer:
