### Question:
XYBoxAndWhiskerRenderer extends AbstractXYItemRenderer implements XYItemRenderer, Cloneable, PublicCloneable, Serializable { @Override public Object clone() throws CloneNotSupportedException { return super.clone(); } XYBoxAndWhiskerRenderer();  XYBoxAndWhiskerRenderer(double boxWidth); double getBoxWidth(); void setBoxWidth(double width); Paint getBoxPaint(); void setBoxPaint(Paint paint); boolean getFillBox(); void setFillBox(boolean flag); Paint getArtifactPaint(); void setArtifactPaint(Paint paint); @Override Range findRangeBounds(XYDataset dataset); @Override void drawItem(Graphics2D g2, XYItemRendererState state,
            Rectangle2D dataArea, PlotRenderingInfo info, XYPlot plot,
            ValueAxis domainAxis, ValueAxis rangeAxis, XYDataset dataset,
            int series, int item, CrosshairState crosshairState, int pass); void drawHorizontalItem(Graphics2D g2, Rectangle2D dataArea,
            PlotRenderingInfo info, XYPlot plot, ValueAxis domainAxis,
            ValueAxis rangeAxis, XYDataset dataset, int series,
            int item, CrosshairState crosshairState, int pass); void drawVerticalItem(Graphics2D g2, Rectangle2D dataArea,
            PlotRenderingInfo info, XYPlot plot, ValueAxis domainAxis,
            ValueAxis rangeAxis, XYDataset dataset, int series,
            int item, CrosshairState crosshairState, int pass); @Override boolean equals(Object obj); @Override Object clone();  }### Answer:
@Test public void testCloning() throws CloneNotSupportedException { XYBoxAndWhiskerRenderer r1 = new XYBoxAndWhiskerRenderer(); XYBoxAndWhiskerRenderer r2 = (XYBoxAndWhiskerRenderer) r1.clone(); assertNotSame(r1, r2); assertSame(r1.getClass(), r2.getClass()); assertEquals(r1, r2); }
