JMenus - Existing User Password and Populating Fields

[Holly Leery]

Hello everyone!! I am having two problems with a JMenu program I am working on. First, the Existing User Panel - I know that I need a for loop to determine if the password entered for an existing user is in the ArrayList Users, however when determining if the password entered is "terminator" (which is the guest password) I do not need it, so I am having trouble determining the best way to set this up. Does anyone have any ideas for me?

class ExistingUserPanel extends JPanel
{
public ExistingUserPanel()
{
JLabel loginnamelabel = new JLabel("Login Name:");
final JTextField loginname = new JTextField(10);
JLabel passwordlabel = new JLabel("Password:");
final JPasswordField passwordfield = new JPasswordField();
JButton signin = new JButton("Sign In");
JButton cancel = new JButton("Cancel");
 
setLayout(new GridLayout(3,2));
add(loginnamelabel);
add(loginname);
add(passwordlabel);
add(passwordfield);
add(signin);
add(cancel);

passwordfield.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
String passwd = new String(passwordfield.getPassword());
 
for (Users user : myList)
{
        if(passwd.equals(user.getPassword()))
        {
        JOptionPane.showMessageDialog(null, "Welcome back, " + loginname.getText() + "!" + "\n\n" + "You are now logged in.", 
        "Login Successful", JOptionPane.INFORMATION_MESSAGE);
passwordfield.setText("");
SessionThread newSession = new SessionThread("thread" + String.valueOf(SalesMenu.i), SalesMenu.container);
SalesMenu.i++;
newSession.start();
SalesMenu.frame.dispose();
         }
        else if(passwd.equals("terminator"))
{
        JOptionPane.showMessageDialog(null, "Hello, welcome to the system!" + "\n\n" + "You are now logged in.", 
        "Login Successful", JOptionPane.INFORMATION_MESSAGE);
passwordfield.setText("");
SessionThread newSession = new SessionThread("thread" + String.valueOf(SalesMenu.i), SalesMenu.container);
SalesMenu.i++;
newSession.start();
SalesMenu.frame.dispose();
}
else
{
JOptionPane.showMessageDialog(null, "The password entered is invalid.  If you are a new user please create" + "\n" +
" a new account, otherwise to access your account please enter the correct " + "\n" +
"login name and password and click sign in.", "Password Invalid", JOptionPane.INFORMATION_MESSAGE);
loginname.setText("");
passwordfield.setText("");
loginname.requestFocus();
}
}
}
});

signin.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
for (Users user : myList)
{
String passwd = new String(passwordfield.getPassword());
        if(passwd.equals(user.getPassword()))
        {
        JOptionPane.showMessageDialog(null, "Welcome back, " + loginname.getText() + "!" + "\n\n" + "You are now logged in.", 
        "Login Successful", JOptionPane.INFORMATION_MESSAGE);
passwordfield.setText("");
SessionThread newSession = new SessionThread("thread" + String.valueOf(SalesMenu.i), SalesMenu.container);
SalesMenu.i++;
newSession.start();
SalesMenu.frame.dispose();
         }
        else if(passwd.equals("terminator"))
{
        JOptionPane.showMessageDialog(null, "Hello, welcome to the system!" + "\n\n" + "You are now logged in.", 
        "Login Successful", JOptionPane.INFORMATION_MESSAGE);
passwordfield.setText("");
SessionThread newSession = new SessionThread("thread" + String.valueOf(SalesMenu.i), SalesMenu.container);
SalesMenu.i++;
newSession.start();
SalesMenu.frame.dispose();
}
else
{
JOptionPane.showMessageDialog(null, "The password entered is invalid.  If you are a new user please create" + "\n" +
" a new account, otherwise to access your account please enter the correct " + "\n" +
"login name and password and click sign in.", "Password Invalid", JOptionPane.INFORMATION_MESSAGE);
loginname.setText("");
passwordfield.setText("");
loginname.requestFocus();
}
}
}
});

cancel.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
frame.setVisible(false);
}
});
}
}

The second thing I am struggling with is populating the data fields in the Current Salesman Panel. I am just not quite sure how to go about this. What I would like to happen is when a user enters the name of a Salesman then their previous entry of information pops up in all of the fields and then the next time their name is entered the newest data after that pops up into the fields. Anyone have any ideas for this part?

class CurrentSalesmanPanel extends JPanel
{
public CurrentSalesmanPanel()
{
JLabel salesmanlabel = new JLabel("Salesman:");
salesmanname = new JTextField(15);
JLabel none1 = new JLabel("");
JLabel amtsoldlabel = new JLabel("Amount Sold:");
amtprodsold = new JTextField(15);
JLabel none2 = new JLabel("");
JLabel prodsoldlabel = new JLabel("Product Sold:");
product = new JComboBox();
JLabel saleslevellabel = new JLabel("Sales Level:");
saleslevel = new JComboBox();
JLabel empty1 = new JLabel("");
JButton updatesalesmandata = new JButton("Update Salesman");
JButton done = new JButton("All Data Entry Done");
JLabel empty2 = new JLabel("");
 
saleslevel.addItem("");
saleslevel.addItem("Entry");
saleslevel.addItem("Junior");
saleslevel.addItem("Senior");

product.addItem("");
product.addItem("Product 1");
product.addItem("Product 2");
product.addItem("Product 3");
product.addItem("Product 4");
product.addItem("Product 5");

setLayout(new FlowLayout());

add(salesmanlabel);
add(salesmanname);
add(none1);
add(amtsoldlabel);
add(amtprodsold);
add(none2);
add(prodsoldlabel);
add(product);
add(saleslevellabel);
add(saleslevel);
add(empty1);
add(updatesalesmandata);
add(done);
add(empty2);

updatesalesmandata.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
addSalesman();
}
});

done.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
frame.setVisible(false);
}
});
}
}

I will post the entire code if anyone needs/wants me to. I wasn't sure if it would be easier to just show the parts that I am unsure of or the whole thing, so if you would like me to post the whole thing I would be happy to. I would greatly appreciate any tips or help anyone could give me. Thank you so much in advance.

Oh also, on a text area called output is their a way to put a JScrollPane? Here is an example of a text area I am using:

class WriteTextFilePanel extends JPanel
{
public WriteTextFilePanel()
{
JLabel none1 = new JLabel("");
JButton writetextfile = new JButton("Write Text File");
JButton cancel = new JButton("Cancel");
JLabel none2 = new JLabel("");
output = new JTextArea(250,300);

output.setVisible(true);
output.setRows(20);
output.setColumns(26);
 
setLayout(new FlowLayout());
 
add(none1);
add(writetextfile);
add(cancel);
add(none2);
add(output);

writetextfile.setToolTipText("Click here to select the text file you want to view and write the Salesman Data to.");
 
writetextfile.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
writeTextFile();
}
});

cancel.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
frame.setVisible(false);
}
});
}
}

Thanks again!!!

I realize my post above was probably not the best, I didn't really know how to post and ask those couple of questions without posting all of that long code. I apologize for that. I have been trying to get that for loop in the existing user panel to work for a couple of days now and I am sure it is ridiculously easy, I just dont see it. I decided to repost just that little part of the code. I am trying to test if guest and terminator are entered by the user (which are the default passwords) and then also if any exitsing user has entered a name a password...for this I check the User array list I created. I know I need to run through the array and that is why I used for (Users user : myList), but it doesn't seem to want to work properly, is there a better way to set up this for loop? Thank you for any help you may be able to give, if you don't have time, I understand.

passwordfield.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
String passwd = new String(passwordfield.getPassword());
 
if(passwd.equals("terminator") && name.getText().equals("guest"))
{
        JOptionPane.showMessageDialog(null, "Hello, welcome to the system!" + "\n\n" + "You are now logged in.", 
        "Login Successful", JOptionPane.INFORMATION_MESSAGE);
passwordfield.setText("");
SessionThread newSession = new SessionThread("Thread" + String.valueOf(SalesMenu.i), SalesMenu.container);
SalesMenu.i++;
newSession.start();
dispose();
}
else 
{
for (Users user : myList)
{
if(passwd.equals(user.getPassword()) && name.getText().equals(user.getLoginName()))
{
JOptionPane.showMessageDialog(null, "Welcome back, " + name.getText() + "!" + "\n\n" + "You are now logged in.", 
"Login Successful", JOptionPane.INFORMATION_MESSAGE);
passwordfield.setText("");
SessionThread newSession = new SessionThread("Thread" + String.valueOf(SalesMenu.i), SalesMenu.container);
SalesMenu.i++;
newSession.start();
dispose();
}
else
{
JOptionPane.showMessageDialog(null, "The password and/or login name entered is invalid.  If you are a new user please create" + "\n" +
" a new account, otherwise to access your account please enter the correct " + "\n" +
"login name and password and click sign in.", "Password Invalid", JOptionPane.INFORMATION_MESSAGE);
name.setText("");
passwordfield.setText("");
name.requestFocus();
}
}
}
}
});

Also, I really do not know what to post for the populating data fields part, I just want to popualte a text field and two combo boxes when a user enters a name into a Salesman Text Field, is there a way of doing this? Maybe there is some reference I could look at. I hope this post is a little better than the long one above. Again, thank you for any help you may be able to point in my direction and for your time. I very much appreciate it.
