如何用Java编写用户注册界面？界面建议用可视化来做java写登陆注册代码，美观且便捷 。下面这个是完全用代码写java写登陆注册代码的，仅供参考 。\x0d\x0aimport javax.swing.*;\x0d\x0aimport java.awt.event.*;\x0d\x0aimport java.awt.*;\x0d\x0aimport java.sql.*;\x0d\x0apublic class Register extends JFrame {\x0d\x0a JLabel jl1 = new JLabel("用户名");\x0d\x0a JTextField jt1 = new JTextField();\x0d\x0a JLabel jl2 = new JLabel("邮箱");\x0d\x0a JTextField jt2 = new JTextField();\x0d\x0a JLabel jl3 = new JLabel("密码");\x0d\x0a JPasswordField jpw1 = new JPasswordField();\x0d\x0a JLabel jl4 = new JLabel("密码确认");\x0d\x0a JPasswordField jpw2 = new JPasswordField();\x0d\x0a JButton register = new JButton("注册");\x0d\x0a JButton clean = new JButton("清空");\x0d\x0a public Register(){\x0d\x0asetLayout(new GridLayout(5,2));\x0d\x0aadd(jl1);\x0d\x0aadd(jt1);\x0d\x0aadd(jl2);\x0d\x0aadd(jt2);\x0d\x0aadd(jl3);\x0d\x0aadd(jpw1);\x0d\x0aadd(jl4);\x0d\x0aadd(jpw2);\x0d\x0aadd(register);\x0d\x0aadd(clean);\x0d\x0aString name = jt1.getText();\x0d\x0aString email = jt2.getText();\x0d\x0aString pw = jpw1.getText();\x0d\x0aregister.addActionListener(new ActionListener(){\x0d\x0apublic void actionPerformed(ActionEvent e){\x0d\x0atry{\x0d\x0aClass.forName("com.mysql.jdbc.Driver");\x0d\x0aConnection con = DriverManager.getConnection("jdbc:mysql://localhost/db","root","");\x0d\x0aStatement sta = con.createStatement();\x0d\x0asta.executeUpdate("INSERT INTO register VALUES(name,email,pw)");\x0d\x0aJOptionPane.showMessageDialog(null,"注册成功","提示",JOptionPane.INFORMATION_MESSAGE);\x0d\x0a}\x0d\x0acatch(Exception ex){\x0d\x0aex.getStackTrace();\x0d\x0a}\x0d\x0a}\x0d\x0a});\x0d\x0aclean.addActionListener(new ActionListener(){\x0d\x0apublic void actionPerformed(ActionEvent e){\x0d\x0ajt1.setText("");\x0d\x0ajt2.setText("");\x0d\x0ajpw1.setText("");\x0d\x0ajpw2.setText("");\x0d\x0a}\x0d\x0a});\x0d\x0a }\x0d\x0a public static void main(String[] args){\x0d\x0aRegister frame = new Register();\x0d\x0aframe.setTitle("用户注册");\x0d\x0aframe.setLocationRelativeTo(null);\x0d\x0aframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);\x0d\x0aframe.setSize(400,400);\x0d\x0aframe.setVisible(true);\x0d\x0a }\x0d\x0a}
