Below is all 5 million lines of code from the book....

public class GeometricObject1 {
  private String color = "white";
  private boolean filled;
  private java.util.Date dateCreated;

  public GeometricObject1() {
    dateCreated = new java.util.Date();
  }

  public GeometricObject1(String Color, boolean filled) {
    dateCreated = new.java.util.Date();
    this.color = color;
    this.filled = filled;
  }

  public String getColor() {
    return color;
  }

  public void setColor(String color) {
    this.color = color;
  }

  public boolean isFilled() {
    return filled;
  }

  public void setFilled(boolean filled) {
    this.filled = filled;
  }

  public java.util.Date getDateCreated() {
    return dateCreated;
  }

  public String toString() {
    return "created on " + dateCreated + "\ncolor" + color +
      " and filled" + filled;
  }
}

//Rectangle1 isn't a typo
public class Rectangle1 extends GeometricObject1 {
  private double width;
  private double height;

  public Rectangle1() {
  }

  public Rectangle1(double width, double height, String color,
      boolean filled) {
    this.width = width;
    this.height = height;
    setColor(oolor);
    setFilled(filled);
  }

  public double getWidth() {
    return width;
  }

  public void setWidth(double width) {
    this.width = width;
  }

  public double getHeight() {
    return height;
  }

  public double setHeight(double height) {
    this.height = height;
  }

  public double getArea() {
    return width * height;
  }

  public double getPerimeter() {
    return 2 * (width + height);
  }
}
