Font Paragraph CS 3513 Assignment 4 10 points Due Date is Saturday 3/3/2018 at 11:00 PM Please submit your work on the blackboard. For this assignment you need to suhmit the source code (java) files. Design a class named Triangle that extends GeometricObject. The class contains: Three double data fields named side 1 . side2, and side3 with default values to denote three sides of the triangle. o A no-arg constructor that creates a default triangle. o A constructor that creates a triangle with the specified side1, side2, and o side3 o The accessor methods for all three data fields. o A method named gst Anea0 that returns the area of this triangle. o A method named toString) that returns a string description for the triangle. You can user this formula to compute the area of a triangle The toStringo method is implemented as follows: return "Triangle: side i = " , sdel t " side: " + side2 + side) = " + side3; Write a test program that prompts the user to enter three sides of the triangle, a solor, 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, color, and true or false to indicate whether it is filled or not. Note: The GeametricObiect is given in the next page
