### Question:
SRTMGL1Provider extends AbstractSRTMElevationProvider { int getMinLatForTile(double lat) { return (int) (Math.floor((90 + lat) / latDegree) * latDegree) - 90; } SRTMGL1Provider();  SRTMGL1Provider(String cacheDir); static void main(String[] args); @Override String toString();  }### Answer:
@Test public void testMinLat() { assertEquals(52, instance.getMinLatForTile(52.5)); assertEquals(29, instance.getMinLatForTile(29.9)); assertEquals(-60, instance.getMinLatForTile(-59.9)); }
