Java GUI实现学生成绩管理系统

学习java有一年多了，一直在做web方面的练习，在一个项目中发现需要用到gui的相关知识，结果没法做出来，网上这方面的文章又不是很多，所有只好自己硬着头皮从头再学一遍了，不过学习后发现，其实gui是非常有趣的，他并不像web程序一样依赖互联网，而且还有许多布局和android相差不是很大，这才发现自己竟又爱上gui的开发了，不多说了，直接上代码吧，相信有过android或相关界面开发的都明白这其中的道理。

先看看效果吧

这样就能轻松实现登录验证了，本打算从数据库读取数据的，由于时间关系，这里就简单的直接验证了，后续有时间的话再做其他的部分。

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持服务器之家。
