### Question:
BuildBarSeries { @SuppressWarnings("unused") public static void main(String[] args) { BarSeries a = buildAndAddData(); System.out.println("a: " + a.getBar(0).getClosePrice().getName()); BaseBarSeriesBuilder.setDefaultFunction(DoubleNum::valueOf); a = buildAndAddData(); System.out.println("a: " + a.getBar(0).getClosePrice().getName()); BarSeries b = buildWithDouble(); BarSeries c = buildWithBigDecimal(); BarSeries d = buildManually(); BarSeries e = buildManuallyDoubleNum(); BarSeries f = buildManuallyAndAddBarManually(); BarSeries g = buildAndAddBarsFromList(); }  @SuppressWarnings("unused") static void main(String[] args);  }### Answer:
@Test public void test() { BuildBarSeries.main(null); }
