public class Rectangle
extends Rectangle2D
implements Shape, Serializable

A Rectangle specifies an area in a coordinate space that is enclosed by the Rectangle object's top-left point (x, y) in the coordinate space, its width, and its height.

A Rectangle object's width and height are public fields. The constructors that create a Rectangle, and the methods that can modify one, do not prevent setting a negative value for width or height.

A Rectangle whose width or height is negative is considered empty. If the Rectangle is empty, then the isEmpty method returns true. No point can be contained by or inside an empty Rectangle. The values of width and height, however, are still valid. An empty Rectangle still has a location in the coordinate space, and methods that change its size or location remain valid. The behavior of methods that operate on more than one Rectangle is undefined if any of the participating Rectangle objects has a negative width or height. These methods include intersects, intersection, and union.

Rectangle(int width, int height)
    Constructs a new Rectangle whose top-left corner is at (0, 0) in the coordinate space, and whose width and height are specified by the arguments of the same name.
Rectangle(int x, int y, int width, int height)
    Constructs a new Rectangle whose top-left corner is specified as (x, y) and whose width and height are specified by the arguments of the same name.
Rectangle(Point p)
    Constructs a new Rectangle whose top-left corner is the specified Point, and whose width and height are both zero.
Rectangle(Point p, Dimension d)
    Constructs a new Rectangle whose top-left corner is specified by the Point argument, and whose width and height are specified by the Dimension argument.
