Question

Java please

Implement a class LoginForm that simulates a login form that you find on many web pages. Supply methods The first input is the user name, the second input is the password. The click method can be called with arguments "Submit" and "Reset". Once a user has been successfully logged in, by supplying the user name, password, and clicking on the submit button, the loggedln method returns true and further input has no effect. When a user tries to log in with an invalid user name and password, the form is reset. Supply a constructor with the expected user name and password.

Explanation / Answer

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Log extends JFrame
{
public static void main(String[] args)
{
Log frameTabel = new Log();
}
JButton blogin = new JButton("Login");
JPanel panel = new JPanel();
JTextField txuser = new JTextField(15);
JPasswordField pass = new JPasswordField(15);
Log()
{
super("Login Autentification");
setSize(300,200);
setLocation(500,280);
panel.setLayout (null);
txuser.setBounds(70,30,150,20);
pass.setBounds(70,65,150,20);
blogin.setBounds(110,100,80,20);
panel.add(blogin);
panel.add(txuser);
panel.add(pass);
getContentPane().add(panel);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
actionlogin();
}
public void actionlogin()
{
blogin.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent ae)
{
String puname = txuser.getText();
String ppaswd = pass.getText();
if(puname.equals("test") && ppaswd.equals("12345"))
{
newframe regFace =new newframe();
regFace.setVisible(true);
dispose();
}
else
{
JOptionPane.showMessageDialog(null,"Wrong Password / Username");
txuser.setText("");
pass.setText("");
txuser.requestFocus();
}
}
});
}
}

and you must save this source below with name "newframe.java"

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class newframe extends JFrame
{
public static void main(String[] args)
{
newframe frameTabel = new newframe();
}
JLabel welcome = new JLabel("Welcome to a New Frame");
JPanel panel = new JPanel();
newframe()
{
super("Welcome");
setSize(300,200);
setLocation(500,280);
panel.setLayout (null);
welcome.setBounds(70,50,150,60);
panel.add(welcome);
getContentPane().add(panel);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
}
}
