Rectangle

public Rectangle()

Rectangle

public Rectangle(int x,
                 int y,
                 int width,
                 int height)
Parameters:
x - the X-coordinate of the Rectangle's top-left corner.
y - the Y-coordinate of the Rectangle's top-left corner.
width - the width of the Rectangle.
height - the height of the Rectangle.

Rectangle

public Rectangle(Point p,
                 int width,
                 int height)
Parameters:
p0 - the top-left corner of the Rectangle.
width - the width of the Rectangle.
height - the height of the Rectangle.

Rectangle

Method Detail

area

public double area()
Description copied from class: Polygon
POLYGON AREA

Overrides:
area in class Polygon

boundingBox

public Rectangle boundingBox()
Shape Implementation

Overrides:
boundingBox in class Polygon

contains

public boolean contains(Point p)
Description copied from class: ConvexPolygon
POINT IN POLYGON TEST

Specified by:
contains in interface Shape
Overrides:
contains in class ConvexPolygon
Parameters:
p - the point we test for encloseness.
Returns:
true iff the point is enclosed in the shape.

getBottomRight

public Point getBottomRight()

getTopLeft

public Point getTopLeft()

perimeter

public double perimeter()
Description copied from class: Polygon
POLYGON PERIMETER

Overrides:
perimeter in class Polygon

toString

public java.lang.String toString()
Returns a string representation of this rectangle. The string is composed of the rectangle label (if any), and the rectangle [topleft,bottomRight] vertices.

Overrides:
toString in class Polygon
Returns:
a string representation of this rectangle.
