Java programming

1. (Triangle class) Design a new Triangle class that extends the abstract
GeometricObject class. Draw the UML diagram for the classes Triangle
and GeometricObject and then implement the Triangle class. 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 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.

    Design a general class GeometricObject can be used to model all geometric objects. This class contains the properties color and filled and their appropriate get and set methods. Assume that this class also contains toString() methods. The toString() method returns a string representation of the object. Define the Triangle, Circle, and Rectangle classes that extend the GeometricObject class. The Triangle class inherits all accessible data fields and methods from the GeometricObject class.In addition, it has three double data fields named...
