如何在htmlunit中创建复选框元素？

import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.*;

public class HtmlUnitExample {
    public static void main(String[] args) throws Exception {
        // 创建WebClient对象
        WebClient webClient = new WebClient();

        // 打开网页
        HtmlPage page = webClient.getPage("http://example.com");

        // 定位复选框元素
        HtmlCheckBoxInput checkBox = page.getFirstByXPath("//input[@type='checkbox']");

        // 创建复选框元素
        HtmlCheckBoxInput newCheckBox = new HtmlCheckBoxInput(checkBox.getPage(), checkBox.getAttributes());

        // 设置复选框状态
        newCheckBox.setChecked(true);

        // 提交表单（可选）
        HtmlForm form = checkBox.getEnclosingForm();
        if (form != null) {
            form.submit();
        }

        // 关闭WebClient
        webClient.close();
    }
}
