学生信息管理系统JAVASE版--1.1.1
现在终于可以写出实用一点的程序了。虽然这个程序的功能非常之简陋，而且还有BUG。不过最起码已经可以使用了。
功能预览和下一步的目标
程序主界面
查询功能：
目前只做了一个表的增、删、改、查。下一步应该就是把功能完善，比如加入错误处理，比如加入成绩部分。完成一个班级内的学生信息管理的功能，应该具有学生的基本信息查询，成绩管理这两个功能
不过有一个问题就是，在表格更新这一部分，每更新一次，就要创建一个tabliModel对象，感觉可以改进。再有就是MVC模式，其实也就接触设计模式。还有就是整成那种可执行文件。
程序代码
mysql建表语句
CREATE TABLE student(
stuId INT PRIMARY KEY,
stuName VARCHAR(20) NOT NULL DEFAULT ‘‘,
stuAge INT NOT NULL DEFAULT 0,
stuSex VARCHAR(5) NOT NULL DEFAULT ‘‘
)engine myisam charset utf8;JAVA代码：
