Запрос: Применяя интерфейсы на языке java написать программу расчета периметра и площади геометрических фигур: круг, прямоугольник, треугольник. Расчет периметра фигур должен быть в качестве default методов в интерфейсе. Задать для каждой фигуры цвет заливки

```java public interface Shape { double calculatePerimeter(); default void printPerimeter() { System.out.println("Perimeter: " + calculatePerimeter()); } } class Circle implements Shape { private double radius; private String fillColor; private String borderColor; public Circle(double radius, String fillColor, String borderColor) { this.radius = radius; this.fillColor = fillColor; this.borderColor = borderColor; } @Override public double calculatePerimeter() { return 2 * Math.PI * radius; } public void printDetails() { System.out.println("Circle:"); printPerimeter(); System.out.println("Fill color: " + fillColor); System.out.println("Border color: " + borderColor); } } class Rectangle implements Shape { private double length; private double width; private String fillColor; private String borderColor; public Rectangle(double length, double width, String fillColor, String borderColor) { this.length = length; this.width = width; this.fillColor = fillColor; this.borderColor = borderColor; } @Override public double calculatePerimeter() { return 2 * (length + width); } public void printDetails() { System.out.println("Rectangle:"); printPerimeter(); System.out.println("Fill color: " + fillColor); System.out.println("Border color: " + borderColor); } } class Triangle implements Shape { private double side1; private double side2; private double side3; private String fillColor; private String borderColor; public Triangle(double side1, double side2, double side3, String fillColor, String borderColor) { this.side1 = side1; this.side2 = side2; this.side3 = side3; this.fillColor = fillColor; this.borderColor = borderColor; } @Override public double calculatePerimeter() { return side1 + side2 + side3; } public void printDetails() { System.out.println("Triangle:"); printPerimeter(); System.out.println("Fill color: " + fillColor); System.out.println("Border color: " + borderColor); } } public class Main { public static void main(String[] args) { Circle circle = new Circle(5, "Red", "Black"); Rectangle rectangle = new Rectangle(4, 6, "Blue", "Green"); Triangle triangle = new Triangle(3, 4, 5, "Yellow", "Purple"); circle.printDetails(); System.out.println(); rectangle.printDetails(); System.out.println(); triangle.printDetails(); } } ``` ```java ``` This program defines an interface `Shape` with a default method `calculatePerimeter` and `printPerimeter`. It also implements three classes `Circle`, `Rectangle`, and `Triangle` that implement the `Shape` interface and provide specific implementations for calculating perimeter of each shape. Each shape class also has additional fields for fill color and border color. The `Main` class creates instances of each shape and prints their details including perimeter, fill color, and border color.
