(The Triangle class) Design a class named Triangle that extend 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. The 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 returnd 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 Programming exercise 2.19 the toString() method is implemented as follows: return “Triangle: side1 = ” + side1 + “side2 = ” + side2 + “side3 = ” + side3: Draw the UML diagram fro the classes Triangle and GeometricObject and implement the classes. Write a 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 Traiangle object with these sides and set the color and filled properties using the input. The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not.
