    Overrides:
      `setRect` in class `Rectangle2D`
    Parameters:
      `r` - the specified `Rectangle2D`
    Since:
      1.2

  - ### outcode

    public int outcode(double x, double y)
    Determines where the specified coordinates lie with respect to this `Rectangle2D`. This method computes a binary OR of the appropriate mask values indicating, for each side of this `Rectangle2D`, whether or not the specified coordinates are on the same side of the edge as the rest of this `Rectangle2D`.
    Specified by:
      `outcode` in class `Rectangle2D`
    Parameters:
      `x` - the specified X coordinate

    See Also:
      - `Rectangle2D.OUT_LEFT`
      - `Rectangle2D.OUT_TOP`
      - `Rectangle2D.OUT_RIGHT`
      - `Rectangle2D.OUT_BOTTOM`

  - ### getBounds2D

    public Rectangle2D getBounds2D()
    Returns a high precision and more accurate bounding box of the `Shape` than the `getBounds` method. Note that there is no guarantee that the returned `Rectangle2D` is the smallest bounding box that encloses the `Shape`, only that the `Shape` lies entirely within the indicated `Rectangle2D`. The bounding box returned by this method is usually tighter than that returned by the `getBounds` method and never fails due to overflow problems since the return value can be an instance of the `Rectangle2D` that uses double precision values to store the dimensions.

    Note that the definition of insideness can lead to situations where points on the defining outline of the `shape` may not be considered contained in the returned `bounds` object, but only in cases where those points are also not considered contained in the original `shape`.

    If a `point` is inside the `shape` according to the `contains(point)` method, then it must be inside the returned `Rectangle2D` bounds object according to the `contains(point)` method of the `bounds`. Specifically:

    `shape.contains(p)` requires `bounds.contains(p)`

    If a `point` is not inside the `shape`, then it might still be contained in the `bounds` object:

    `bounds.contains(p)` does not imply `shape.contains(p)`

    Specified by:
      `getBounds2D` in interface `Shape`
    Overrides:
      `getBounds2D` in class `Rectangle2D`
    Returns:
      an instance of `Rectangle2D` that is a high-precision bounding box of the `Shape`.
    Since:
      1.2

  - ### createIntersection

    public Rectangle2D createIntersection(Rectangle2D r)
    Returns a new `Rectangle2D` object representing the intersection of this `Rectangle2D` with the specified `Rectangle2D`.
    Specified by:
      `createIntersection` in class `Rectangle2D`
    Parameters:
      `r` - the `Rectangle2D` to be intersected with this `Rectangle2D`
    Returns:
      the largest `Rectangle2D` contained in both the specified `Rectangle2D` and in this `Rectangle2D`.
    Since:
      1.2

  - ### createUnion

    public Rectangle2D createUnion(Rectangle2D r)
    Returns a new `Rectangle2D` object representing the union of this `Rectangle2D` with the specified `Rectangle2D`.
    Specified by:
      `createUnion` in class `Rectangle2D`
    Parameters:
      `r` - the `Rectangle2D` to be combined with this `Rectangle2D`
    Returns:
      the smallest `Rectangle2D` containing both the specified `Rectangle2D` and this `Rectangle2D`.
    Since:
      1.2
