Design a class named Triangle that extends Geometricobject. The class contains: Three double data fields named side1, side2, and side 3 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: return "Triangle: side 1= " + side1 + " side 2= " + side2 + 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
