PLEASE USE JAVA PROGRAMMING

Problem Description: 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 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, The tostring_(.) method is implemented as follows: 1. Draw the UML diagram that involves the classes Triangle and GeometricObject. 2. Implement the class. 3. 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
