### Question:
XYStepRenderer extends XYLineAndShapeRenderer implements XYItemRenderer, Cloneable, PublicCloneable, Serializable { @Override public boolean equals(Object obj) { if (obj == this) { return true; } if (!(obj instanceof XYLineAndShapeRenderer)) { return false; } XYStepRenderer that = (XYStepRenderer) obj; if (this.stepPoint != that.stepPoint) { return false; } return super.equals(obj); } XYStepRenderer();  XYStepRenderer(XYToolTipGenerator toolTipGenerator,
            XYURLGenerator urlGenerator); double getStepPoint(); void setStepPoint(double stepPoint); @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 int hashCode(); @Override Object clone();  }### Answer:
@Test public void testEquals() { XYStepRenderer r1 = new XYStepRenderer(); XYStepRenderer r2 = new XYStepRenderer(); assertEquals(r1, r2); r1.setStepPoint(0.44); assertFalse(r1.equals(r2)); r2.setStepPoint(0.44); assertEquals(r1, r2); r1.setDefaultCreateEntities(false); assertFalse(r1.equals(r2)); r2.setDefaultCreateEntities(false); assertEquals(r1, r2); }
