### Question:
XYErrorRenderer extends XYLineAndShapeRenderer { public void setErrorPaint(Paint paint) { this.errorPaint = paint; fireChangeEvent(); } XYErrorRenderer(); boolean getDrawXError(); void setDrawXError(boolean draw); boolean getDrawYError(); void setDrawYError(boolean draw); double getCapLength(); void setCapLength(double length); Paint getErrorPaint(); void setErrorPaint(Paint paint); Stroke getErrorStroke(); void setErrorStroke(Stroke stroke); @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);  }### Answer:
@Test public void testCloning() throws CloneNotSupportedException { XYErrorRenderer r1 = new XYErrorRenderer(); r1.setErrorPaint(new GradientPaint(1.0f, 2.0f, Color.RED, 3.0f, 4.0f, Color.WHITE)); XYErrorRenderer r2 = (XYErrorRenderer) r1.clone(); assertNotSame(r1, r2); assertSame(r1.getClass(), r2.getClass()); assertEquals(r1, r2); }
