Problems importing Java packages in JSP

The last time I wrote a JSP guide, there were two errors ( what?). There are two places ..., in a word ... ), so here's what you want to record:

The new JSP file will automatically generate a sentence:

<%@ page language= "java" import= "java.util.*" pageencoding= "UTF-8"%>

Then we need to import the packages we want:

One-to-one import:

<%@ page language= "java" import= "java.sql.*"%>
<%@ page language= "java" import= "java.util.regex.*"%>

A piece of import:

<%@ page import= "java.sql.*,java.util.regex.*"%> in the middle with commas separated, followed by commas!

The mistake I made myself was:

The first place is:

<%@ page language= "java" import= "java.util.*" pageencoding= "UTF-8"%>
<%@ page language= "java" import= "java.sql.*" pageencoding= "UTF-8"%>

Is it a weird feeling?
