public Rectangle2D createIntersection(Rectangle2D r)

Return a new rectangle which is the intersection of this and the given one. The result will be empty if there is no intersection.

Overrides:- createIntersection in interface Rectangle2D

Parameters:`r`

- the rectangle to be intersected

Returns:- the intersection

Throws:`NullPointerException`

- if r is null

public Rectangle2D createUnion(Rectangle2D r)

Return a new rectangle which is the union of this and the given one.

Overrides:- createUnion in interface Rectangle2D

Parameters:`r`

- the rectangle to be merged

Returns:- the union

Throws:`NullPointerException`

- if r is null

public Rectangle2D getBounds2D()

Returns the bounds of this rectangle. A pretty useless method, as this is already a rectangle.

Specified by:- getBounds2D in interface Shape

Overrides:- getBounds2D in interface Rectangle2D

Returns:- a copy of this rectangle

public double getHeight()

Return the height.

Overrides:- getHeight in interface RectangularShape

Returns:- the value of height

public double getWidth()

Return the width.

Overrides:- getWidth in interface RectangularShape

Returns:- the value of width

public double getX()

Return the X coordinate.

Overrides:- getX in interface RectangularShape

Returns:- the value of x

public double getY()

Return the Y coordinate.

Overrides:- getY in interface RectangularShape

Returns:- the value of y

public boolean isEmpty()

Test if the rectangle is empty.

Overrides:- isEmpty in interface RectangularShape

Returns:- true if width or height is not positive

public int outcode(double x, double y)

Determine where the point lies with respect to this rectangle. The result will be the binary OR of the appropriate bit masks.

Overrides:- outcode in interface Rectangle2D

Parameters:`x`

- the x coordinate to check`y`

- the y coordinate to check

Returns:- the binary OR of the result

Since:- 1.2

public void setRect(double x, double y, double w, double h)

Set the contents of this rectangle to those specified.

Overrides:- setRect in interface Rectangle2D

Parameters:`x`

- the x coordinate`y`

- the y coordinate`w`

- the width`h`

- the height

public void setRect(Rectangle2D r)

Set the contents of this rectangle to those specified.

Overrides:- setRect in interface Rectangle2D

Parameters:`r`

- the rectangle to copy

Throws:`NullPointerException`

- if r is null
