public class Rectangle

extends ShapeImpl

implements Shape

A rectangle shape. The main operations are to read the x and y coordinates of the upper-left corner of the rectangle (getX() and getY()), to change the position of the rectangle (moveBy(...) and moveTo(...)), to rotate the position of the rectangle around some point (rotateAround(...)), to read and change the color of the rectangle (getColor() and setColor(...)), to read and change the width and height of the rectangle (getWidth(), getHeight(), and resize(...)), and add to and remove from a GWindow (addTo(...) and removeFromWindow()). Other operations are mainly for internal use, and should not be called by regular client programs.

Constructor Summary

Rectangle()
Create a new, filled rectangle, colored red, with a default location and size.

Rectangle(int x, int y, int width, int height)
Create a new unfilled, black rectangle with the given position and size.

Rectangle(int x, int y, int width, int height, java.awt.Color c, boolean fill)
Create a new rectangle of the given position, size, color, and filledness.

Method Summary

int	getHeight() Return the height of the rectangle
int	getWidth() Return the width of the rectangle
int	getX() Return the X coordinate of the rectangle's upper-left corner
int	getY() Return the Y coordinate of the rectangle's upper-left corner
boolean	intersects(Rectangle r) Return whether the argument rectangle intersects this rectangle
void	moveTo(int x, int y) Move the upper-left corner of the rectangle to the given coordinates.
void	paint(java.awt.Graphics g) Paint this shape onto the given graphics context.
void	resize(int newWidth, int newHeight) Change the width and height of the rectangle
java.lang.String	toString() Answer the printed representation of this shape.
