Error: Calendar cannot be resolved in JSP
提问by greenthunder
I tried to get date in JSP like what I searched before, but it didn't work. Here is my code.
我试图像我之前搜索的那样在 JSP 中获取日期，但是没有用。这是我的代码。
<%@ page contentType="text/html; charset=utf-8" language="java" import="java.sql.*, java.text.*;" errorPage="" %>
<%!
DateFormat tipe = new SimpleDateFormat("EEE, MMM d, ''yy");
Calendar cal = Calendar.getInstance();
%>
<%
out.print(tipe.format(cal.getTime()));
%>
Why it said "Calendar cannot be resolved"? Where's the mistake?
为什么它说“日历无法解决”？错在哪里？

Calendaris in a java.utilpackage. You are missing import.
Calendar在一个java.util包中。您缺少导入。
