### Question:
SeriesYNumberRecalculator implements SeriesYRecalculator { @Override public Series<Object, ? extends Number> recalculateSeries(Series<Object, Integer> series, JudgmentSeriesCriteria criteria, XSettings xsettings, YSettings ysettings) { return series; }  @Override Series<Object, ? extends Number> recalculateSeries(Series<Object, Integer> series, JudgmentSeriesCriteria criteria, XSettings xsettings, YSettings ysettings); @Override boolean handles(YValueType yValueType);  }### Answer:
@Test public void recalculateSeries() { Series<Object, Integer> series = new Series<>(); Series<Object, ? extends Number> recalcSeries = recalculator.recalculateSeries(series, new JudgmentSeriesCriteria(), new XSettings(), new YSettings()); assertTrue(series == recalcSeries); }
