### Question:
CategoryStepRenderer extends AbstractCategoryItemRenderer implements Cloneable, PublicCloneable, Serializable { @Override public boolean equals(Object obj) { if (obj == this) { return true; } if (!(obj instanceof CategoryStepRenderer)) { return false; } CategoryStepRenderer that = (CategoryStepRenderer) obj; if (this.stagger != that.stagger) { return false; } return super.equals(obj); } CategoryStepRenderer();  CategoryStepRenderer(boolean stagger); boolean getStagger(); void setStagger(boolean shouldStagger); @Override LegendItem getLegendItem(int datasetIndex, int series); @Override void drawItem(Graphics2D g2,
                         CategoryItemRendererState state,
                         Rectangle2D dataArea,
                         CategoryPlot plot,
                         CategoryAxis domainAxis,
                         ValueAxis rangeAxis,
                         CategoryDataset dataset,
                         int row,
                         int column,
                         int pass); @Override boolean equals(Object obj); static final int STAGGER_WIDTH; }### Answer:
@Test public void testEquals() { CategoryStepRenderer r1 = new CategoryStepRenderer(false); CategoryStepRenderer r2 = new CategoryStepRenderer(false); assertEquals(r1, r2); r1 = new CategoryStepRenderer(true); assertFalse(r1.equals(r2)); r2 = new CategoryStepRenderer(true); assertEquals(r1, r2); }
