  // Example 23-3: Using a java.awt.Rectangle object
  
  // This sketch uses two Rectangle objects. 
  Rectangle rect1, rect2;
  
  void setup() {
    size(200,200);
    // The arguments for the constructor (x,y,width,height) are documented in the Java reference: 
    // http://java.sun.com/j2se/1.4.2/docs/api/java/awt/Rectangle.html.
    rect1 = new Rectangle(25,25,50,50); 
    rect2 = new Rectangle(125,75,50,75);
  }
  
  void draw() {
    background(255);
    stroke(0);
    
    // The contains() function is used to determine if the mouse is located inside the rectangle.
    if (rect1.contains(mouseX,mouseY)) { 
      fill(200);
    } else {
      fill(100);
    }
    
    // A Rectangle object only knows about the variables associated with a rectangle. 
    // It cannot display itself and so we use Processing's rect() function in combination with the Rectangle's data.
    rect(rect1.x, rect1.y, rect1.width,rect1.height); 
    
    // Repeat for the second Rectangle
    // (Of course, we could use an array or ArrayList here!)
    if (rect2.contains(mouseX,mouseY)) {
      fill(200);
    } else {
      fill(100);
    }
    rect(rect2.x, rect2.y, rect2.width,rect2.height);
  }
