Design a class named Triangle subclass of GeometricObject from the lecture notes that contains:
Three double data fields named side1, side2, and side3 with default values 1.0 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.
Draw the UML diagram that involves the class Triangle. Implement the class. Write a test program that creates a Triangle object with sides 1, 1.5, 1, sets color yellow and filled true, and displays the area, perimeter, color, and whether filled or not.
