### Question:
CountryBordersPolygon { public MultiPolygon getBoundary() { return this.boundary; } CountryBordersPolygon(String name, Geometry boundary); double[] getBBox(); boolean shares(MultiPolygon other); boolean crossesBoundary(LineString line); String getName(); MultiPolygon getBoundary(); boolean inBbox(Coordinate c); boolean inArea(Coordinate c); double getArea();  }### Answer:
@Test public void TestBoundaryGeometry() { MultiPolygon boundary = cbp.getBoundary(); Coordinate[] cbpCoords = boundary.getCoordinates(); assertEquals(country1Geom.length, cbpCoords.length); assertEquals(country1Geom[0].x, cbpCoords[0].x, 0.0); assertEquals(country1Geom[3].y, cbpCoords[3].y,0.0); }
