Develop an implementation of your Rectangle API from EXERCISE 3.2.1 that takes advantage of the Interval data type to simplify and clarify the code.

Data From in Exercise 3.2.1

Consider the following data-type implementation for axis-aligned rectangles, which represents each rectangle with the coordinates of its center point and its width and height:

public class Rectangle { } private final double x, y; private final double width; private final double height; // center of rectangle // width of rectangle // height of rectangle public Rectangle (double x0, double y0, double w, double h) { X = x0; y = yo; width = w; height = h; } public double area() { return width * height; } public double perimeter() { /* Compute perimeter. */ } public boolean intersects (Rectangle b) { /* Does this rectangle intersect b? */ } public boolean contains (Rectangle b) { /* Is b inside this rectangle? */ } public void draw(Rectangle b) { /* Draw rectangle on standard drawing. */ } representation height intersects contains (x, y) width a
