例如这段代码,怎么把它写成若干个独立的java文件,比如一个是控制类,作用是连接数据库写入数据。一个是边界类,生成界面。另一个是实体类,生成用户的实例。最后写一个main进行测试呢? package mypackage; import javax.swing.*; import java.sql.*; import java.awt.*; import java.awt.event.*; public class Test extends JFrame { /** * @param args */ JLabel username; JLabel password; JLabel repassword; JLabel age; JLabel name; JLabel lname; JTextField usertext; JPasswordField passwordtext; JPasswordField repasswordtext; JTextField agetext; JButton submit; JRadioButton man; JRadioButton woman; String sex="男"; public Test() { Container c=this.getContentPane(); GridBagLayout gbl=new GridBagLayout(); GridBagConstraints gbc= new GridBagConstraints(); c.setLayout(gbl); gbc.anchor=GridBagConstraints.WEST; username=new JLabel("用 户 名 : "); gbc.gridx=0; gbc.gridy=0; gbl.setConstraints(username,gbc); c.add(username); usertext=new JTextField(15); gbc.gridx=1; gbc.gridy=0; gbl.setConstraints(usertext,gbc); c.add(usertext); password=new JLabel("密 码 : "); gbc.gridx=0; gbc.gridy=1; gbl.setConstraints(password,gbc); c.add(password); passwordtext=new JPasswordField(15); passwordtext.setEchoChar('*'); gbc.gridx=1; gbc.gridy=1; gbl.setConstraints(passwordtext,gbc); c.add(passwordtext); repassword=new JLabel("确认密码 : "); gbc.gridx=0; gbc.gridy=2; gbl.setConstraints(repassword,gbc); c.add(repassword); repasswordtext=new JPasswordField(15); passwordtext.setEchoChar('*'); gbc.gridx=1; gbc.gridy=2; gbl.setConstraints(repasswordtext,gbc); c.add(repasswordtext); name=new JLabel("性 别 :"); gbc.gridx=0; gbc.gridy=3; gbl.setConstraints(name,gbc); c.add(name); Panel p=new Panel(); p.setLayout(new FlowLayout()); final ButtonGroup bg=new ButtonGroup(); man=new JRadioButton("男",true); woman=new JRadioButton("女"); p.add(man); p.add(woman); c.add; bg.add(man); bg.add(woman); gbc.gridx=1; gbc.gridy=3; gbl.setConstraints(p,gbc); age=new JLabel("年 龄 :"); gbc.gridx=0; gbc.gridy=4; gbl.setConstraints(age,gbc); c.add(age); agetext=new JTextField(15); gbc.gridx=1; gbc.gridy=4; gbl.setConstraints(agetext,gbc); c.add(agetext); lname=new JLabel(" "); gbc.gridx=1; gbc.gridy=5; gbl.setConstraints(lname,gbc); c.add(lname); submit=new JButton("注册"); gbc.gridx=1; gbc.gridy=6; gbl.setConstraints(submit,gbc); c.add(submit); final ImageIcon p1=new ImageIcon("SmsMsgSomeFail.gif"); final ImageIcon p2=new ImageIcon("SmsMsgFail.gif"); class MyListener implements ActionListener { public void actionPerformed(ActionEvent e) { try { if(e.getSource()==submit) { Connection con; PreparedStatement ptm; ResultSet rs; Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); String url="jdbc:odbc:mydb"; con=DriverManager.getConnection(url,"",""); String name,age,pas,repas; name=usertext.getText(); pas=new String(passwordtext.getPassword()); repas=new String(repasswordtext.getPassword()); age=agetext.getText(); if(pas.equals(repas)){ ptm=con.prepareStatement("insert into users values(?,?,?,?)"); ptm.setString(1,name); ptm.setString(2,pas); ptm.setString(3,age); ptm.setString(4,sex); ptm.executeUpdate(); JOptionPane.showMessageDialog(null,"注册成功 !欢迎您的加入 !","信息提示",JOptionPane.PLAIN_MESSAGE,p1); ptm.close(); con.close(); } else{ JOptionPane.showMessageDialog(null, "两次输入密码不相同 !", "错误提示",JOptionPane.PLAIN_MESSAGE,p2); } } else { sex=((JRadioButton)(e.getSource())).getText(); } } catch(Exception ae){} } } MyListener mylistener=new MyListener(); submit.addActionListener(mylistener); man.addActionListener(mylistener); woman.addActionListener(mylistener); } public static void main(String[] args) { // TODO 自动生成方法存根 Test enrolfram=new Test(); enrolfram.setTitle("新用户注册"); enrolfram.setResizable(false); enrolfram.setSize(300,300); enrolfram.setVisible(true); } } 我疑惑的是几个java文件是如何进行参数传递和协同工作的,望高手指点。谢谢了。
