Design a class named Triangle that extends GeometricObject. The class 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 rectangle 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, 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 prompts the user to enter three sides of the triangle, a color and a Boolean value to indicate whether the triangle is filled. The program should create a Triangle object with these sides and set the color and filled properties using the input. The program should display the area, perimeter, color and true/false to indicate whether it is filled or not.
