Problem Description: Design a class named Triangle that extends 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. A constructor that creates a triangle with the specified side1, side2, and side3. The get and set 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. The toString() method is implemented as follows:

return"Triangle:side1="+side1+"side2="+side2+-"side3="+side3; Coding: Submit the following items: 1. Implement the class Triangle. 2. Run the test program (Assignment1 show below) that creates a Triangle object with sides 1,1.5,1, colour yellow and filled true, and displays the area, perimeter, colour, and whether filled or not. 3. Compile, Run, and take a screenshot of the output and submit to Blackboard (you must submit the program regardless whether it complete or incomplete, correct or incorrect) 4. Add and commit the Java file in the Git repository (step 4 of Question 1). Take a screenshot showing your execution of the Git commands. 5. Draw a class diagram to model GemetricObject and triangles. In addition to triangle, the diagram should model rectangle, square, oval, and circle. However, not all objects can be colored. Only rectangles, squares and triangles can be colored
