Question

I need some help with this assigmet.

Design a class named Triangle that extends GeometricObject. The class contains:
Three double data fields named side1, side2, and side3 with default values Q to denote three sides of the triangle.
A no-arg constructor that creates a default triangle.
• A constructor that creates a triangle with the specified side1, side2, and side3.
• The accessor methods for all three data fields.
A method named getArea() that returns the area of this triangle.
• A method named getPerimeter() that returns the perimeter of this triangle.
• A method named toString(), that returns a string description for the triangle.
For the formula to compute the area of a triangle, see Exercise 5.19. The toString() method is implemented as follows:
return "Triangle: side1 = " + side1 + " side2 = " + side2 +" side3 = " + side3;
Draw the UML diagram that involves the classes Triangle and GeometricObject. Implement the class. Write a test
program that creates a Triangle object with sides 1, 1.5, 1, color yellow and filled true, and displays the area, perimeter,
color, and whether filled or not.

Expert Solution

Step 1

Steps to be followed:

Create a class named GeometricObject
- Declare two variables: String color and Boolean filled.
- Define the default constructor.
- Define parameterized constructor to initialize both fields.
- Define the getter and setter method for each data field.
- Override toString() method.
Create a Triangle class that extends GeometricObject
- Declare three double data fields: double side1, side2, side3.
- Define the default constructor.
- Define parameterized constructor to initialize all three fields.
- Define the getter and setter method for each data field.
- Define getArea() method to return the area of a triangle.
- Define getPerimeter() method to return the perimeter of a triangle.
- Override toString() method.
Create Main class
- Create Triangle class's object.
- Call methods of Triangle class and GeometricObject class and print result.
