### Question:
ClusteredXYBarRenderer extends XYBarRenderer implements Cloneable, PublicCloneable, Serializable { @Override public Object clone() throws CloneNotSupportedException { return super.clone(); } ClusteredXYBarRenderer();  ClusteredXYBarRenderer(double margin,
                                  boolean centerBarAtStartValue); @Override int getPassCount(); @Override Range findDomainBounds(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); @Override boolean equals(Object obj); @Override Object clone();  }### Answer:
@Test public void testCloning() throws CloneNotSupportedException { ClusteredXYBarRenderer r1 = new ClusteredXYBarRenderer(); ClusteredXYBarRenderer r2 = (ClusteredXYBarRenderer) r1.clone(); assertNotSame(r1, r2); assertSame(r1.getClass(), r2.getClass()); assertEquals(r1, r2); }
