### Question:
WindItemRenderer extends AbstractXYItemRenderer implements XYItemRenderer, Cloneable, PublicCloneable, Serializable { @Override public Object clone() throws CloneNotSupportedException { return super.clone(); } WindItemRenderer(); @Override void drawItem(Graphics2D g2,
                         XYItemRendererState state,
                         Rectangle2D plotArea,
                         PlotRenderingInfo info,
                         XYPlot plot,
                         ValueAxis domainAxis,
                         ValueAxis rangeAxis,
                         XYDataset dataset,
                         int series,
                         int item,
                         CrosshairState crosshairState,
                         int pass); @Override Object clone();  }### Answer:
@Test public void testCloning() throws CloneNotSupportedException { WindItemRenderer r1 = new WindItemRenderer(); WindItemRenderer r2 = (WindItemRenderer) r1.clone(); assertNotSame(r1, r2); assertSame(r1.getClass(), r2.getClass()); assertEquals(r1, r2); }
