### Question:
Circle implements Shape { @Override public GHPoint getCenter() { return new GHPoint(lat, lon); } Circle(double lat, double lon, double radiusInMeter);  Circle(double lat, double lon, double radiusInMeter, DistanceCalc calc); double getLat(); double getLon(); @Override boolean contains(double lat1, double lon1); @Override BBox getBounds(); @Override GHPoint getCenter(); @Override boolean intersects(Shape o); @Override boolean intersects(PointList pointList); @Override boolean contains(Shape o); boolean intersects(BBox b); boolean intersects(Circle c); boolean contains(BBox b); boolean contains(Circle c); @Override double calculateArea(); @Override boolean equals(Object obj); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void testGetCenter() { Circle c = new Circle(10, 10, 10); GHPoint center = c.getCenter(); assertEquals(10, center.getLat(), .00001); assertEquals(10, center.getLon(), .00001); }
