Design and Implementation of Graphic Interface

# Introduction

In this challenge, we will focus on designing and implementing a Graphic Interface using Java. We will create an interface called "Figure" that will serve as a standard for various plane shapes, such as rectangles and triangles. This interface will define abstract methods for calculating the perimeter and area of these shapes. Additionally, we will implement concrete requirements in classes derived from this interface, namely the "Rectangle" and "Triangle" classes.
