Description:
This problem is driving me crazy...can you help??
Build a class heirarchy based on the abstract class TwoDShape, defined below:
TwoDShape abstract definition
public abstract class TwoDShape{
protected double area, perimeter;
protected String name;
public TwoDShape(String n){
area=0;
perimeter=0;
name=n;
}// constructor
public abstract double computeArea();
public abstract double computePerimeter();
public double getArea(){retrun area;}// getarea
public double getPerimeter(){return perimeter;}// get perimeter
public String toString(){
return name;
}//toString
}//twodshape
Design a concrete class Circle, which will extend from the abstract class.
Also, design a class MyRectangle extended from TwoDShape, as well as a class called Square
extended from My Rectangle. Design the classes to make maximum use of inherited methods and
members and not have to re-invent everything at every class level.
Circle class: This class will have a constructor that will accept a double. That double
will be the radius of the cirlce. It will also have a private double data member called
radius. It must be designed so that the radius can never be set to less than 1. If any attempt
is made to set the radius <1, the radius should be set to 1. Use get and set methods for the
radius, as well as a toString method that returns a string announcing that it is a circle and
giving it's area and perimeter. (use Math class PI).
MyRectangle class: Should have 2 protected double data members, length and width. It will have
a constructor that requires two doubles (length and width). Be sure the length and width cannot
be less than 1. As in the circle, set it to 1, if less than 1. Use set and get methods for length
and width. It's toString method will announce it's a rectangle and give the area and perimeter.
Square: Will have a constructor that accepts a single double, the length of a side. Again, the
side should never be smaller than 1. The square will have a getSide and setSide method.
NOTE: Be sure the get and set methods are inherited from My Rectangle.
The test program for the project will be an application, and need not be interactive. It should
instantiate one each of the concrete classes and test the methods. Use an array of TwoDShapes that
wil be used to reference the instantiated objects and further test them, insuring that polymorphism
works. Use a TextArea on a scroll pane for your output.
Deliverables:
Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
Complete copyrights to all work purchased.
The documentation for this project will consist of an html file created by javaDoc on the Square
class. Each method defined in that class must have javadoc comments for display.
The docs will use parameter and author tags as appropriate.
Platform:
Windows
Special Conditions / Other:
Must be complete and delivered on 07/17/2002 by 4:00 PM EST

I can do this in a couple of hours.
I guarantee very clear source code with appropriate comments.
Just choose my bid and you will have the code developed in time.
Regards,
Andrei |
