### Question:
EllipseGeometry extends PolygonGeometry { @Override public EllipseGeometry clone() { return (EllipseGeometry)super.clone(); } EllipseGeometry(EllipseGeometry.AngleBuilder<?> builder, PolygonRenderProperties renderProperties,
            Constraints constraints);  EllipseGeometry(EllipseGeometry.Builder<?> builder, PolygonRenderProperties renderProperties, Constraints constraints);  EllipseGeometry(EllipseGeometry.FocusBuilder<?> builder, PolygonRenderProperties renderProperties,
            Constraints constraints);  EllipseGeometry(EllipseGeometry.ProjectedBuilder builder, PolygonRenderProperties renderProperties,
            Constraints constraints); protected  EllipseGeometry(PolygonGeometry.Builder<?> builder, PolygonRenderProperties renderProperties,
            Constraints constraints); @Override EllipseGeometry clone(); @Override Builder<? extends Position> createBuilder(); @Override EllipseGeometry derive(BaseRenderProperties renderProperties, Constraints constraints); @Override Position getReferencePoint();  }### Answer:
@Test public void testClone() { EllipseGeometry.AngleBuilder<GeographicPosition> builder = new EllipseGeometry.AngleBuilder<GeographicPosition>(); builder.setDataModelId(3423L); GeographicPosition position = new GeographicPosition(LatLonAlt.createFromDegrees(23., 56.)); builder.setCenter(position); builder.setAngle(45.); builder.setSemiMajorAxis(23f); builder.setSemiMinorAxis(26f); builder.setLineSmoothing(true); builder.setLineType(LineType.GREAT_CIRCLE); builder.setRapidUpdate(true); PolygonRenderProperties renderProperties1 = new DefaultPolygonRenderProperties(65763, false, true); TimeConstraint timeConstraint = TimeConstraint.getTimeConstraint(TimeSpan.get(10L, 20L)); Constraints constraints1 = new Constraints(timeConstraint); EllipseGeometry geom = new EllipseGeometry(builder, renderProperties1, constraints1); EllipseGeometry clone = geom.clone(); Assert.assertNotSame(geom, clone); Assert.assertEquals(geom.getDataModelId(), clone.getDataModelId()); Assert.assertEquals(geom.isLineSmoothing(), clone.isLineSmoothing()); Assert.assertEquals(geom.getLineType(), clone.getLineType()); Assert.assertEquals(geom.getVertices(), clone.getVertices()); Assert.assertEquals(geom.isRapidUpdate(), clone.isRapidUpdate()); Assert.assertNotSame(geom.getRenderProperties(), clone.getRenderProperties()); Assert.assertEquals(geom.getRenderProperties(), clone.getRenderProperties()); Assert.assertNotSame(geom.getConstraints(), clone.getConstraints()); Assert.assertEquals(geom.getConstraints(), clone.getConstraints()); }
