### Question:
Boxplot { private static double[] sort(double[] values) { Arrays.sort(values); return values; } Boxplot(Double[] values);  Boxplot(Collection<Double> values);  Boxplot(double[] values); double median(); double q1(); double q3(); InterquatileRange innerFences(); InterquatileRange outerFences(); InterquatileRange fences(double m); double[] getValues(); double[] getValues(InterquatileRange fence); double[] filter(Predicate<Double> p);  }### Answer:
@Test public void testSort() { assertArrayEquals(new double[] { 69, 69, 70, 70, 70, 70, 71, 71, 71, 72, 73, 300 }, this.boxplot.getValues(), 0.0); }
