编写一个表单页面census.html，让用户填写姓名、性别（男女选择）、兴趣（运动，读书，音乐，书法及其他）

能帮我回答一下嘛。发到[email protected]
上述表单提交给Servlet来处理该表单程序，并回送用户的填写结果。
要求调试并能够运行结果。显示结果为：
您的姓名是：
您的性别是：
您的兴趣爱好是：
根据census.html，利用Servlet的相应方法和web.xml配置，实现Form表单内容的读取。Servlet中的doGet()方法和doPost() 方法都要定义。要求写出census.html和Servlet文件和web.xml关于servlet的配置代码。
