### Question:
VectorRenderer extends AbstractXYItemRenderer implements XYItemRenderer, Cloneable, PublicCloneable, Serializable { @Override public Object clone() throws CloneNotSupportedException { return super.clone(); } VectorRenderer(); @Override Range findDomainBounds(XYDataset dataset); @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); @Override boolean equals(Object obj); @Override Object clone();  }### Answer:
@Test public void testCloning() throws CloneNotSupportedException { VectorRenderer r1 = new VectorRenderer(); VectorRenderer r2 = (VectorRenderer) r1.clone(); assertNotSame(r1, r2); assertSame(r1.getClass(), r2.getClass()); assertEquals(r1, r2); }
