The software I use is Eclipse, please teach me how to use it on Eclipse.

1. Design a class named Triangle that extends GeometricObject class (attached with this Lab) The class contains Three double data fields named side1, side2, and side3 with default values 1.0 to denote three sides of a triangle. .A no-arg constructor that creates a default triangl A constructor that creates a triangle with 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 area of this triangle. .A method named toString0 that returns a string description for the triangle. The formula for computing the area of a triangle is: side1 +side2 +side3 , area s(s - side1)(s - side2) (s - side3) The toString0 method is implemented as follows: return "Triangle: side sidel + "sideside2 side3side3; Write a test 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 creates 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
