### Question:
CountryBordersHierarchy { public double[] getBBox() { return new double[] {minLon, maxLon, minLat, maxLat}; }  void add(CountryBordersPolygon cp); boolean inBbox(Coordinate c); double[] getBBox(); List<CountryBordersPolygon> getPolygons(); List<CountryBordersPolygon> getContainingPolygons(Coordinate c);  }### Answer:
@Test public void GetBBoxTest() { double[] bbox = cbh1.getBBox(); assertEquals(-1.0, bbox[0], 0.0); assertEquals(1.0, bbox[1], 0.0); assertEquals(-1.0, bbox[2], 0.0); assertEquals(1.0, bbox[3], 0.0); bbox = cbh2.getBBox(); assertEquals(5.0, bbox[0], 0.0); assertEquals(10.0, bbox[1], 0.0); assertEquals(5.0, bbox[2], 0.0); assertEquals(10.0, bbox[3], 0.0); }
