public class Insertmysql {

public static final String[] WEEK = {"00","日","一","二","三","四","五","六"};

public static void main(String[] args)

e.printStackTrace();

}

try {

Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/envp", "root", "root");

System.out.println("Success connect Mysql server!");

Statement statement = connection.createStatement();

while(rSet.next())

String hour = rSet.getString("date");

String hString = hour.substring(11, 13);

Calendar cal = Calendar.getInstance();
