### Question:
XYBoxAndWhiskerRenderer extends AbstractXYItemRenderer implements XYItemRenderer, Cloneable, PublicCloneable, Serializable { @Override public boolean equals(Object obj) { if (obj == this) { return true; } if (!(obj instanceof XYBoxAndWhiskerRenderer)) { return false; } if (!super.equals(obj)) { return false; } XYBoxAndWhiskerRenderer that = (XYBoxAndWhiskerRenderer) obj; if (this.boxWidth != that.getBoxWidth()) { return false; } if (!PaintUtils.equal(this.boxPaint, that.boxPaint)) { return false; } if (!PaintUtils.equal(this.artifactPaint, that.artifactPaint)) { return false; } if (this.fillBox != that.fillBox) { return false; } return true; } 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,

@Test public void testEquals() { XYBoxAndWhiskerRenderer r1 = new XYBoxAndWhiskerRenderer(); XYBoxAndWhiskerRenderer r2 = new XYBoxAndWhiskerRenderer(); assertEquals(r1, r2); r1.setArtifactPaint(new GradientPaint(1.0f, 2.0f, Color.green, 3.0f, 4.0f, Color.RED)); assertFalse(r1.equals(r2)); r2.setArtifactPaint(new GradientPaint(1.0f, 2.0f, Color.green, 3.0f, 4.0f, Color.RED)); assertEquals(r1, r2); r1.setBoxWidth(0.55); assertFalse(r1.equals(r2)); r2.setBoxWidth(0.55); assertEquals(r1, r2); r1.setFillBox(!r1.getFillBox()); assertFalse(r1.equals(r2)); r2.setFillBox(!r2.getFillBox()); assertEquals(r1, r2); r1.setBoxPaint(Color.yellow); assertFalse(r1.equals(r2)); r2.setBoxPaint(Color.yellow); assertEquals(r1, r2); r1.setBoxPaint(null); assertFalse(r1.equals(r2)); r2.setBoxPaint(null); assertEquals(r1, r2); }
