Creating an Abstract Class Shape I
Option #1: Creating an Abstract Class Shape I
Create an abstract class “Shape” with the following specifications:
- An abstract method “surface_area ()” of return type double
- An abstract method “volume()” of return type double
Put your code in a Java source file named “Shape.java.”
I.
Create a class “Sphere” that extends the Shape class with the following specifications:
- Attributes:
- Radius
- Constructor:
- Implement a parameterized constructor needed to initialize the data.
- toString:
- Implement a “toString” method that prints out the surface area and volume.
Implement methods to compute the surface area and volume.
II.
Create a class “Cylinder” that extends the Shape class with the following specifications:
- Attributes:
- Radius, height – both of type double
- Constructor:
- Implement a parameterized constructor to initialize the data.
- toString:
- Implement a “toString” method that prints out the surface area and volume.
Implement methods to compute the surface area and volume.
III.
Create a class “Cone” that extends the Shape class with the following specifications:
- Attributes:
- Radius, height – both of type double
- Constructor:
- Implement a parameterized constructor to initialize the data.
- toString:
- Implement a “toString” method that prints out the surface area and volume.
Implement methods to compute the surface area and volume.
IV.
Create a driver class named “ShapeArray” with the following specifications:
- Instantiate one sphere.
- Instantiate one cylinder.
- Instantiate one cone.
- Store the class instances into an array named “shapeArray.”
- Loop through the array and print out the instance data of each object using the object instance’s “toString” method.
