### 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); }
