哪位大神帮下，测试连接数据库，这些错误是什么意思？

Exception in thread "main" com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'imooc.imooc' doesn't exist

代码如下package com.iooc.db;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class DBUtil {

   private static final String URL="jdbc:mysql://127.0.0.1:3306/imooc";
   private static final String USER="root";
   private static final String PASSWORD="admin";

   public static void main(String[] args) throws Exception {

       //1、加载驱动程序
       Class.forName("com.mysql.jdbc.Driver");
       //2、获得数据库的连接
       Connection conn= DriverManager.getConnection(URL, USER, PASSWORD);
       //3、通过数据库的连接操作数据库，实现增删改查
       Statement stmt= conn.createStatement();
       ResultSet rs= stmt.executeQuery("Select user_name,age from imooc_goddess");

       while(rs.next()){
           System.out.println(rs.getString("user_name"+","+rs.getInt("age")));

       }
   }


}
