Source Code

CIRCLE

public class Circle extends Shape { private double radius; // Default constructor public Circle() { super(); // calling the super-class default constructor initializes the color to 'green' radius = 1.0; } // Overloaded constructor public Circle(double rad, String col) { super(col); // call super-class constructor with the given color setRadius(rad); } // getters and setters public double getRadius() {return radius;} public void setRadius(double new_radius) { if(new_radius < 0) // if the given radius is negative, set it to 1.0 { new_radius = 1.0; } radius = new_radius; } // methods public double getArea() { return Math.PI*Math.pow(getRadius(), 2); } @Override public String toString() { return String.format("A Circle with radius=%.2f, which is a subclass of %s", getRadius(), super.toString()); } }

DRIVER

public class Driver { public static void main(String[] args) throws Exception { // Create a red Circle with radius -1 Circle circle = new Circle(-1, "red"); // If we print it, it should display a radius of 1.0 not -1 System.out.println("This circle is " + circle.getColor()); // print color System.out.println(circle.toString()); System.out.println(String.format("Area: %.2f", circle.getArea())); System.out.println(""); // Create a yellow circle of radius 2 circle = new Circle(2.0, "yellow"); System.out.println("This circle is " + circle.getColor()); // print color System.out.println(circle.toString()); System.out.println(String.format("Area: %.2f", circle.getArea())); System.out.println(""); // Rectangles // Create a rectangle with width = 5 and length = 2 Rectangle rect = new Rectangle(5.0,2.0,"black"); System.out.println(rect.toString()); System.out.println(String.format("Area: %.2f", rect.getArea())); System.out.println(""); // Create a rectangle with negative values. Both its width and length should be setted to 1 rect = new Rectangle(-100, -500, "white"); System.out.println(rect.toString()); System.out.println(""); } }

RECTANGLE

import java.lang.ref.WeakReference; import javax.sql.rowset.WebRowSet; public class Rectangle extends Shape { private double width; private double length; // No-arg constrcutor public Rectangle() { super(); width = 1.0; length = 1.0; } // Overloaded constructor public Rectangle(double w, double l, String col) { super(col); setWidth(w); setLength(l); } // getters and setters public double getWidth() { return width; } public void setWidth(double w) { if(w < 0.0) { w = 1.0; } width = w; } public double getLength() { return length; } public void setLength(double l) { if(l < 0.0) { l = 1.0; } length = l; } // methods public double getArea() {return getWidth()*getLength();} @Override public String toString(){ return String.format("A Rectangle with width=%.2f and length=%.2f, which is a subclass of %s", getWidth(), getLength(), super.toString()); } }

SHAPE

public class Shape { protected String color; // default constructor public Shape() { color = "green"; } // Overloaded constructor public Shape(String col) { color = col; } // getter and setter public void setColor(String new_color) { color = new_color;} public String getColor() {return color;} // toString @Override public String toString() { return "A Shape with color " + getColor(); } }
