昨天有个粉丝朋友也想学开发Web和小程序、安卓,问可以在大学学会吗?

在学校学到的东西真的有限:

在很多的高校,有一些教授是学院派的,他们没有做过多少开发工作,上课就是照本宣科,讲的知识点都是陈年落伍的技术,更别说带学生做项目了。

现在的很多硕博学生帮老师做课件,然后老师上课一顿读。

当然有的老师开发能力也是很强的,他们有开发经验,可以更加全面地理解技术知识点,然后传递给学生,也能拿到一些科研项目,然后带学生实战。

但是,但是,这种老师少之又少。我平时辅导过大量的计算机学生,也有个VIP群,很多学习VIP项目的小伙伴,也变得越来越强,

我总结出来,大部门计算机教学水平真的一般般:

1,教材落后,还有很多Java课程在教Swing/SSH框架,这已经是淘汰多少年的技术了。

2,实战不足。学生在大学期间代码量极少,少得可怜,没有项目实战。找工作和企业的要求无法匹配。

3,教授课程方式极其落后。这是计算机啊,不是汇报工作,你全课程ppt有啥用。是念ppt学生能理解,还是给学生实操下项目,学生可以理解????

4,课后辅导比较差。在国外的一些名校,老师每周抽出三个小时作为 office hour,国内的老师下课,直接拍屁股走人,课后没有辅导。

昨天没事,开发了一个APP的财务系统,如果需要学习开发,可以一起啊!加油,奥利给!

一,系统的技术栈

移动端,采用安卓进行开发,Android它应用于安卓系统软件和程序开发,其由谷歌公司推出,目前在国际市场上有着广泛的应用及开发环境,并不瘦限制研发人员能够通过修改开放的源代码来实现各种使用的 APP软件,开发的软件程序具有界面友好稳定性好等特点,安卓系统架构图具体如下:

后端采用的Java进行开发的,数据库采用的Mysql。

系统的功能架构:

二,系统界面



后台:





三,系统核心代码
