Im trying to create a very simple banking system with swing. I have three classes so far, they are Gui, Main, and Validate.
My problem seem to be when i try to log in. The user/pass i created and stored in the Validate class. I'm getting a wrong password or username, why? What goes wrong?
To get the login popup(JOptionPane), you have to click the "LOG IN" button.
Here is the code for all three classes:
THE MAIN CLASS:
public class Main{
public static void main(String[] args){
Validate validate = new Validate();
Gui gui = new Gui(validate);
//create Accounts. Send accounts to gui+validate.
}
}
THE VALIDATE CLASS:
public class Validate {
Map<String,String> userMap;
public Validate(){
userMap = new HashMap<String,String>();
//Skapa ett inloggning för mig
//accounts.createUser();
userMap.put("john","smith");
}
public boolean validateUser(String username, String password){
if(userMap.isEmpty() != true){
if(userMap.containsKey(username)){
String passTest = userMap.get(username);
if(password.equals(passTest)){
return true;
//accounts.logInUser();
}else{
return false;
}
}else{
return false;
}
}else{
return false;
}
}
}
THE GUI CLASS:
public class Gui extends JFrame implements ActionListener{
JPanel loggning, center, botten;
JButton loggaIn, loggaUt;
JTextField text1, text2;
JLabel lb1, lb2;
JMenuBar mbar;
JMenu about,system;
JMenuItem aboutBank, exit;
Font font;
Validate validate;
public Gui(Validate validate){
super("BANK");
this.validate = validate;
//Skapa menun.
mbar = new JMenuBar();
system = new JMenu("System");
mbar.add(system);
about = new JMenu("About");
mbar.add(about);
aboutBank = new JMenuItem("Bank Info");
about.add(aboutBank);
aboutBank.addActionListener(this);
exit = new JMenuItem("Exit");
exit.addActionListener(this);
system.add(exit);
add(mbar, BorderLayout.NORTH);
//skapa vänstra panelen. Här loggar man in/ut.
loggning = new JPanel();
loggning.setLayout(new GridLayout(20,1,0,5));
text1 = new JTextField("");
text2 = new JTextField("");
lb1 = new JLabel(" ANGE ANVÄNDARNAMN: ");
lb2 = new JLabel(" ANGE LÖSENORD: ");
Border border = BorderFactory.createLineBorder(Color.gray, 1);
lb1.setBorder(border);
lb2.setBorder(border);
//loggning.add(lb1);
//loggning.add(text1);
//loggning.add(lb2);
//loggning.add(text2);
loggaIn = new JButton("Logga in");
loggaUt = new JButton("Logga ut");
loggaUt.setEnabled(false);
loggaIn.setPreferredSize(new Dimension(100,10));
loggaUt.setPreferredSize(new Dimension(100,10));
loggaIn.addActionListener(this);
loggaUt.addActionListener(this);
loggning.add(loggaIn);
loggning.add(loggaUt);
add(loggning, BorderLayout.WEST);
//Skapa mittpanelen. Här finns information om dig och dina konton.
center = new JPanel();
add(center, BorderLayout.CENTER);
//skapa botten panelen. Här kan man ändra i sina konton. Skicka pengar, Dra ut pengar, ändra info? osv.
//JFrame fixeringar
setDefaultCloseOperation(EXIT_ON_CLOSE);
setVisible(true);
setSize(900,900);
}
@Override
public void actionPerformed(ActionEvent e) {
if(e.getSource() == loggaIn){
JTextField user = new JTextField();
JTextField pass = new JTextField();
Object[] message = {"Enter your username:", pass, "Enter your password:", user};
int option = JOptionPane.showConfirmDialog(this, message, "Enter all your values", JOptionPane.OK_CANCEL_OPTION);
if (option == JOptionPane.OK_OPTION)
{
String pass1 = pass.getText();
String user1 = user.getText();
Boolean valid = validate.validateUser(user1,pass1);
if(valid == true){
loggaIn.setEnabled(false);
loggaUt.setEnabled(true);
showLogInInfo(user1);
//accounts.getLoggedInInfo();
//gui.showLoggedInInfo();
//Logged in info showed in center jpanel.
}else{
JOptionPane.showMessageDialog(this,"Username or password wrong", "Error", JOptionPane.INFORMATION_MESSAGE);
}
}
}else if(e.getSource() == loggaUt){
loggaIn.setEnabled(true);
loggaUt.setEnabled(false);
//accounts.gotOutUser();
//text1.setEditable(true);
//text2.setEditable(true);
}else if(e.getSource() == exit){
this.dispose();
}else if(e.getSource() == aboutBank){
String mssg = "Ali Bank.\nSince 2014.\nIf you have questions,\nthere is no customer service.\nSorry we cant help you.";
JOptionPane.showMessageDialog(this, mssg, "Bank Information",JOptionPane.INFORMATION_MESSAGE);
}else{}
}
public void showLogInInfo(String user){
String messs = ("User " + user + " is now logged in.");
JOptionPane.showMessageDialog(this, messs, "Log In Info", JOptionPane.INFORMATION_MESSAGE);
}
}
Some comments may be in Swedish, sorry. Mostly I think they are irrelevant, but if you have a question, please ask.
