求教！dateFormat.parse cannot be resolved to a type
我想判断数据库里是否有date为今日日期的记录，然后做判断，下面是我的代码（不规范，请见谅！）
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>
<%@ page import=" java.io.*"%>

Connection connection=DriverManager.getConnection(url);
Statement statement = connection.createStatement();
request.setCharacterEncoding("gb2312");
String datetime=new SimpleDateFormat("yyyy-MM-dd").format(Calendar.getInstance().getTime());
java.util.Date date = new dateFormat.parse(datetime);
String sql="select date from ssop where date='"+date+"'";
Integer resultnumber=statement.executeUpdate(sql);

statement.close();
connection.close();%>
<p><a href="SSOP_report_show.jsp">（如果您的浏览器无法自动跳转，请点击这里。）</a></p></td>
</tr>
</table>
</body>
</html>
一下是报错内容：
org.apache.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: 20 in the jsp file: /before_deal_material_detection_add.jsp
dateFormat.parse cannot be resolved to a type
17: Statement statement = connection.createStatement();
18: request.setCharacterEncoding("gb2312");
19: String datetime=new SimpleDateFormat("yyyy-MM-dd").format(Calendar.getInstance().getTime());
20: java.util.Date date = new dateFormat.parse(datetime);
21: String sql="select date from ssop where date='"+date+"'";
22: Integer resultnumber=statement.executeUpdate(sql);
23: %>
好像要实现将string转换成date的包我都导入了啊，请指教！
------解决方案--------------------
DateFormat df = new SimpleDateFormat("yyyy-MM-dd");
String date = df.format(new Date());
------解决方案--------------------
String datetime=new SimpleDateFormat("yyyy-MM-dd").format(Calendar.getInstance().getTime());
20: java.util.Date date = new dateFormat.parse(datetime);
这个地方改为：
DateFormat df = new SimpleDateFormat(&quo
