在Java语言中，如何将x和y坐标从XML文件解析为Point2D数组？

    // 创建DOM解析器
    DocumentBuilder builder = factory.newDocumentBuilder();
    // 解析XML文件，获取文档对象
    Document document = builder.parse("your_xml_file.xml");

    // 获取根节点
    Element root = document.getDocumentElement();
    
    // 获取所有坐标节点
    NodeList nodeList = root.getElementsByTagName("坐标");

    // 创建Point2D数组
    Point2D[] points = new Point2D[nodeList.getLength()];
    
    // 遍历坐标节点
    for (int i = 0; i < nodeList.getLength(); i++) {
        Element element = (Element) nodeList.item(i);
        // 获取x坐标
        double x = Double.parseDouble(element.getElementsByTagName("x").item(0).getTextContent());
        // 获取y坐标
        double y = Double.parseDouble(element.getElementsByTagName("y").item(0).getTextContent());
        // 创建Point2D对象并赋值
        points[i] = new Point2D.Double(x, y);
    }

    // 打印Point2D数组
    for (Point2D point : points) {
        System.out.println(point);
    }
} catch (Exception e) {
    e.printStackTrace();
