ich komme einfach nicht auf die uhrsache des fehlers hier der code und fehlerausgabe wenn jemand was findet  
Fehlerhafte Methode:

public boolean equals(Object other) {
if (this == other) return true;
    if (!(other instanceof Polygon)) return false;
    Polygon otherPolygon = (Polygon) other;

    // Check if both polygons are empty
    if (this.points.isEmpty() || otherPolygon.points.isEmpty()) {
        return false;
    }

    // Check if the number of points is the same
    if (this.points.size() != otherPolygon.points.size()) {
        return false;
    }

    // Check if the points in the same order are equal
    for (int i = 0; i < points.size(); i++) {
        if (!this.points.get(i).equals(otherPolygon.points.get(i))) {
            return false;
        }
    }

    return true;
}

Main Methode:

package einfprog;

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        // Test der Implementierung 

        // Testfall 1: Leeres Polygon sollte nicht gleich einem anderen leeren Polygon sein
        ArrayList<Point> emptyPoints1 = new ArrayList<>();
        ArrayList<Point> emptyPoints2 = new ArrayList<>();

        Polygon emptyPolygon1 = new Trigon(emptyPoints1); // Verwende eine konkrete Implementierung wie Trigon
        Polygon emptyPolygon2 = new Trigon(emptyPoints2); // Verwende eine konkrete Implementierung wie Trigon

        System.out.println("Empty Polygon1: " + emptyPolygon1);
        System.out.println("Empty Polygon2: " + emptyPolygon2);
        System.out.println("Empty Polygon1 equals Empty Polygon2: " + emptyPolygon1.equals(emptyPolygon2)); // Erwartet false
        System.out.println();

        // Testfall 2: Trigon mit verschiedenen Punkten
        ArrayList<Point> points3 = new ArrayList<>();
        points3.add(new Point(1, 1));
        points3.add(new Point(2, 2));
        points3.add(new Point(3, 3));

        Trigon trigon1 = new Trigon(points3);

        System.out.println("Trigon1: " + trigon1);
        System.out.println("Circumference: " + trigon1.getCircumference());
        System.out.println("Area: " + trigon1.getArea());
        System.out.println("Is Rectangle: " + trigon1.isRectangle());
    }
}

Fehlermeldung:
Part 1 -- 10/11 tests passed: Point: Success Point.equals(): Success Point.getDistance(): Success Point.toString(): Success Polygon: Success Polygon.equals(): Failed: Expected true for [] and [], but was false Polygon.getCircumference(): Success Polygon.repair(): Success Polygon.clean(): Success Polygon.toString(): Success new Trigon(): Success
