Since:
  1.2

### Double

public Double(double x, double y, double w, double h)
Constructs and initializes an `Ellipse2D` from the specified coordinates.

Parameters:
  `x` - the X coordinate of the upper-left corner of the framing rectangle
  `y` - the Y coordinate of the upper-left corner of the framing rectangle
  `w` - the width of the framing rectangle
  `h` - the height of the framing rectangle
Since:

## Method Details

### getX

public double getX()
Returns the X coordinate of the upper-left corner of the framing rectangle in `double` precision.

Specified by:
  `getX` in class `RectangularShape`
Returns:
  the X coordinate of the upper-left corner of the framing rectangle.
Since:
  1.2

### getY

public double getY()
Returns the Y coordinate of the upper-left corner of the framing rectangle in `double` precision.

Specified by:
  `getY` in class `RectangularShape`
Returns:
  the Y coordinate of the upper-left corner of the framing rectangle.
Since:
  1.2

### getWidth

public double getWidth()
Returns the width of the framing rectangle in `double` precision.

Specified by:
  `getWidth` in class `RectangularShape`
Returns:
  the width of the framing rectangle.
Since:
  1.2

### getHeight

public double getHeight()
Returns the height of the framing rectangle in `double` precision.

Specified by:
  `getHeight` in class `RectangularShape`

Parameters:
  `x` - the X coordinate of the upper-left corner of the specified rectangular shape
  `y` - the Y coordinate of the upper-left corner of the specified rectangular shape
  `w` - the width of the specified rectangular shape
  `h` - the height of the specified rectangular shape
Since:
  1.2

  - `RectangularShape.getFrame()`

### 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`
Returns:
  an instance of `Rectangle2D` that is a high-precision bounding box of the `Shape`.

  1.2
