Java实现简单个人信息录入
一、语言和环境
A、实现语言
Java
B、环境要求
JBuilder 2005（英文版），SQL Server 2000及其联机帮助文档
二、要求
利用SWING编程，要求如下：
1、程序运行的结果的初始界面如图1所示
图1
框架（JFrame）大小为（400,200）
2、输入姓名，选择性别和输入年龄，点击“确定“按钮后，○1在下面的JTextArea区域内显示输入的内容 ，JTextArea组件的大小为（80,30）；○2并且把数据新增至数据库表中（数据库作为考试资源提供学生）。见图2
图2
3、不输入姓名，在下边的提示栏中显示’”姓名不能为空”，个人的信息不在JTextArea里显示，如图3
图3
三、实现步骤(仅作为推荐，不作强制要求)
1、 建立一个JAVA 类PersonInfoRecorder，应当：
A、 继承JFrame
B、 实现ActionListener接口
2、正确定义PersonInfoRecorder类的成员变量
A、定义四个标签（JLabel）:用来显示姓名、性别、年龄和提示栏
B、定义两个文本框JTextField，用来输入姓名和年龄
C、定义一个JComboBox变量，用来选择性别
D、定义一个JTextArea变量，用来显示输入的个人信息
E、定义一个确定按钮
F、定义四个JPanel 面板
3、正确实现PersonInfoRecorder类的构造方法
A、 正确调用父类构造函数;
B、 实例化定义的各个变量;
C、正确设置布局管理器为BorderLayout ;
D、正确添加各组件。
提示:将姓名、性别、年龄和确认按钮等相关组件添加到一个面板中，再把这个面板添加到contentPane的北边，确认按钮一定要注册监听器；在contentPane的南边的面板上添加提示栏;将JTextArea组件添加到contentPane的中部
4、正确实现ActionListener接口的事件处理方法actionPerformed(ActionEvent e)
A、 正确获取录入的数据：姓名、性别和年龄的值
B、 正确检验空数据：如果姓名为空，在提示栏标签中提示” 姓名不能为空！”,返回
C、正确显示录入的数据: 将姓名、性别和年龄用逗号分隔显示在JTextArea中；
D、把数据作为一条记录保存进数据库中（数据源名称统一为：Person）
5、编写main方法
A、 创建一个PersonInfoRecorder对象；
B、 设置personInfoRec的大小（400，200）; 展开
数据库就要你自己建了.
