### isEmpty

public boolean isEmpty()
Determines whether the `RectangularShape` is empty. When the `RectangularShape` is empty, it encloses no area.

Specified by:
  `isEmpty` in class `RectangularShape`
Returns:
  `true` if the `RectangularShape` is empty; `false` otherwise.
Since:
  1.2

### setRect

public void setRect(double x, double y, double w, double h)
Sets the location and size of this `Rectangle2D` to the specified `double` values.

Specified by:
  `setRect` in class `Rectangle2D`
Parameters:
  `x` - the X coordinate of the upper-left corner of this `Rectangle2D`
  `y` - the Y coordinate of the upper-left corner of this `Rectangle2D`
  `w` - the width of this `Rectangle2D`
  `h` - the height of this `Rectangle2D`
Since:

### setRect

public void setRect(Rectangle2D r)
Sets this `Rectangle2D` to be the same as the specified `Rectangle2D`.

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
  `y` - the specified Y coordinate
Returns:
  the logical OR of all appropriate out codes.
Since:
  1.2

  - `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

  - `Shape.getBounds()`

### 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

### toString

public String toString()
Returns the `String` representation of this `Rectangle2D`.

Overrides:
  `toString` in class `Object`
Returns:
  a `String` representing this `Rectangle2D`.
