Program Plan Intro

Rectangle.java

Program Plan:

• Include a class name named “Exercise_13_10”.
  • Declare the main() method.
  • Create three rectangle objects and assign values to them using the Rectangle class.
  • Display the area of each circle object referencing Rectangle class.
  • Display if Rectangle1 is equal to Rectangle 2 or not by referencing Rectangle class.
  • Close the main() method.
  • Close the class.
• Include an abstract class “GeometricObject”.
  • Declare all the data types of the variables.
  • Construct a default geometric object.
  • Construct a geometric object with color and filled value.
  • Assign color and fill to the object.
  • Set a new color.
  • Define an isFilled method returns filled and since filled is Boolean; the get method is named isFilled.
  • Set a new filled and getDateCreated method.
  • Override toString function to return output.
  • Define Abstract method getArea.
  • Define Abstract method getPerimeter.
  • Close class.
• Include a class “Rectangle” that extends the class GeometricObject and implements Comparable.
  • Declare width and height of rectangle.
  • Create a Rectangle constructor.
  • Assign values to height and width.
  • Assign rectangle values to all attributes.
  • Create a function to return width.
  • Create a function to return radius.
  • Create a function to set a new width.
  • Create a function to return height.
  • Create a function to set a new height.
  • Create an override function to return area.
  • Create an override function to return Perimeter.
  • Create an override function that returns true if objects area is the same.
  • Create an override function to implement compareTo method.
  • Close class.
