### Question:
BBox { public BBox() { } BBox();  BBox(int xmin, int ymin, int xmax, int ymax);  BBox(BBox bbox); void shrink(int xShrink, int yShrink); int getWidth(); int getHeight(); void remap(Point offset); boolean contains(Point p); boolean overlaps(BBox box); int getXmin(); void setXmin(int xmin); int getXmax(); void setXmax(int xmax); int getYmin(); void setYmin(int ymin); int getYmax(); void setYmax(int ymax); @Override int hashCode(); @Override boolean equals(Object obj);  }### Answer:
@Test public void testBBox() { BBox bbox = new BBox(); assertEquals(0, bbox.getXmin()); assertEquals(0, bbox.getXmax()); assertEquals(0, bbox.getYmin()); assertEquals(0, bbox.getYmax()); }
