身份证信息录入
知识要点:
关于身份证的录入，我们先的掌握，身份证号码代表的属性 ，在通过属性的定义进行程序编写。同时也得注意算法。
package f;
import javax.swing.*;
import java.awt.*;
public class RegisterTest extends JFrame{//创建类RegisterTest继承于类JFrame
JPanel pnlMain;
JLabel lblUser,lblPassword,lblSurePassword,lblSex,lblIdentify,lblHobby,lblCity;
JTextField txtUser;
JPasswordField pwdPassword1,pwdPassword2;
JRadioButton rbtnMale,rbtnFemale;
JCheckBox chk1,chk2,chk3;
ButtonGroup grpSex;
JButton btnExit,btnLogin;
List lstSize;
JComboBox cmbType;
String[] strType= {“身份证”,”学生证”};//6~15行：定义变量
public RegisterTest(){
super(“注册页面”);//设置页面标题
lblUser=new JLabel(“用户名”);
lblPassword=new JLabel(“密 码”);
lblSurePassword=new JLabel(“确认密码”);
lblUser.setSize(getMaximumSize());
lblSex=new JLabel(“性 别”);
lblIdentify=new JLabel(“有效证件”);
lblHobby=new JLabel(“爱 好”);
lblCity=new JLabel(“城 市”);//18~25行：定义标签
txtUser=new JTextField(10);
pwdPassword1=new JPasswordField(10);
pwdPassword2=new JPasswordField(10);//26~28行：定义文本框和密码框
grpSex=new ButtonGroup();
rbtnMale=new JRadioButton(“男”);
grpSex.add(rbtnMale);
rbtnMale.setSelected(true);
rbtnFemale=new JRadioButton(“女”);
grpSex.add(rbtnFemale);//29~34行：定义单选按钮
cmbType=new JComboBox(strType);
cmbType.setSelectedIndex(0);//35~36行：定义下拉列表框
chk1=new JCheckBox(“运动”);
chk2=new JCheckBox(“唱歌”);
chk3=new JCheckBox(“篮球”);//37~39行：定义复选框
lstSize=new List();
lstSize.add(“南京”);
lstSize.add(“苏州”);
lstSize.add(“东京”);
lstSize.add(“上海”);
lstSize.add(“杭州”);
lstSize.add(“扬州”);
lstSize.add(“徐州”);
lstSize.select(0);//40~48定义列表
JButton btnLogin = new JButton(“确定”);
Component btnExit = new JButton(“取消”);//49~50行：定义“确定”和“取消”按钮
pnlMain=new JPanel();
pnlMain.add(lblUser);
pnlMain.add(txtUser);

this.setContentPane(pnlMain);
setSize(300,330);
setVisible(true);//设置页面的大小、可见性等性质
}
public static void main(String[] args) {
// TODO Auto-generated method stub
new RegisterTest();
}
}
总结：
通过学习，熟悉和掌握了这个程序。
