Java 计算两个多边形重叠面积

可以使用如下的Java代码来计算两个多边形的重叠面积：\n\njava\nimport java.awt.*;\nimport java.util.ArrayList;\nimport java.util.List;\n\npublic class OverlappingArea {\n public static void main(String[] args) {\n // 创建两个多边形\n List<Point> polygon1 = new ArrayList<>();\n polygon1.add(new Point(0, 0));\n polygon1.add(new Point(0, 4));\n polygon1.add(new Point(4, 4));\n polygon1.add(new Point(4, 0));\n\n List<Point> polygon2 = new ArrayList<>();\n polygon2.add(new Point(2, 2));\n polygon2.add(new Point(2, 6));\n polygon2.add(new Point(6, 6));\n polygon2.add(new Point(6, 2));\n\n // 计算重叠面积\n double overlappingArea = calculateOverlappingArea(polygon1, polygon2);\n System.out.println("重叠面积为：" + overlappingArea);\n }\n\n // 计算两个多边形的重叠面积\n public static double calculateOverlappingArea(List<Point> polygon1, List<Point> polygon2) {\n // 根据多边形的顶点，创建多边形对象\n Polygon poly1 = new Polygon();\n for (Point p : polygon1) {\n poly1.addPoint(p.x, p.y);\n }\n\n Polygon poly2 = new Polygon();\n for (Point p : polygon2) {\n poly2.addPoint(p.x, p.y);\n }\n\n // 计算重叠面积\n Area area1 = new Area(poly1);\n area1.intersect(new Area(poly2));\n\n return area1.isEmpty() ? 0 : area1.getBounds().getWidth() * area1.getBounds().getHeight();\n }\n}\n\n\n这个代码示例创建了两个多边形，然后调用calculateOverlappingArea方法计算它们的重叠面积。calculateOverlappingArea方法接受两个多边形的顶点列表作为参数，然后使用java.awt.Polygon类创建多边形对象。最后，计算两个多边形的重叠面积，并返回结果。
