Hello, this is Java programming language assignment. I would appreciate it if you could write it in a way that I can copy paste. It's a bit of a long assignment so I won't forget to give feedback afterwards. Thank you

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 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 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.

For the formula to compute the area of a triangle, The toString() method is implemented as follows:

return "Triangle: side1 = " + side1 + " side2 = " + side2 +

" side3 = " + side3;

1.Draw the UML diagram that involves the classes Triangle and GeometricObject.

2.Implement the class.

3,Write a test program that creates a Triangle object with sides 1, 1.5, 1, color yellow and filled true, and displays the area, perimeter, color, and whether filled or not.
