### Question:
Region { public boolean contains(Number value) { return value.doubleValue() >= getMin().doubleValue() && value.doubleValue() <= getMax().doubleValue(); } Region();  Region(Number v1, Number v2); static Region withDefaults(Region defaults); void setMinMax(Region region); static Number measure(Number v1, Number v2); Number length(); boolean contains(Number value); boolean intersects(Region region); Number center(); Number transform(double value, Region region2); Number transform(double value, Region region2, boolean flip); double transform(double value, double min, double max, boolean flip); Number ratio(Region r2); double ratio(double min, double max); void union(Number value); void union(Region input); void intersect(Region input); boolean intersects(Number line2Min, Number line2Max); boolean isMinSet(); Number getMin(); void setMin(Number min); boolean isMaxSet(); Number getMax(); void setMax(Number max); boolean isDefined(); @Override String toString();  }### Answer:
@Test public void testContains() throws Exception { }
