cs java programs


1. {50 points}Design a new Triangle class that extends the abstract class GeometricObject class. Write a test program that prompts the user to enter the 3 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 or false to indicate whether it is filled or not. (s=side) Area of a triangle = Square-root of ((s*(s-1)*(s-2)*(s-3)).
