### Question:
Grid implements Iterable<Grid.Point> { public int getHeight() { return calculateDistance(getRows()); } Grid(final int padding,
                final int iconSize,
                final int rows,
                final int cols); Point findPosition(final Point anchorPoint,
                              final Direction direction); Point findPosition(final int row,
                              final int col); @Override Iterator<Point> iterator(); int getRows(); int getCols(); int size(); int getWidth(); int getHeight();  }### Answer:
@Test public void testGetHeight() { assertEquals(910, grid.getHeight()); }
