I am creating a login window for a program. I am having trouble getting my program to search through my arraylist and return a username and then search again for a password.

The code is supposed to run the program when the "Login" button is pressed but it currently isn't working.
Below line has a problem :
if (list.get(i).password.equals(passwordField.getPassword())){
JPasswordField#getPassword() return char[] where as you are comparing a String password with char[] that is wrong.
Try Arrays.equals() to compare arrays as follow:
Arrays.equals(list.get(i).password.toCharArray(), passwordField.getPassword());
I suggest you to use Map in place of ArrayList. Make username as key of Map.
Use
Map<String,Login> map = new HashMap<String,Login>();
instead of
ArrayList<Login> list= new ArrayList<Login>();
Map is more faster in search than ArrayList.
I hope that my notes can be helpful :
There is no main method to make the class runnable
The location of list.add(test); is not allowed there. It should be in constructor/method.

I want to assign dir array to comboBox. Is there any error in my code. I tried to display the dir array it contains the values but cannot assign it comboBox. Here is the code.

You can use setModel with DefaultComboBoxModel which take an array instead like :
comboBox.setModel(new DefaultComboBoxModel(dir));
Most of the code posted is not relevant to the question asked, so it should be removed (see MCVE).
Review the following, note the comments:
public class ExpenseManager {
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
#Override
public void run() {
try {
new ExpenseManager();
} catch (Exception e) { e.printStackTrace(); }

}
public ExpenseManager() { initialize(); }

JFrame frame = new JFrame();
frame.setBounds(100, 100, 450, 300);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(null); //better use a layout manger
JComboBox<String> comboBox = new JComboBox<>();
comboBox.setBounds(24, 138, 72, 20);
comboBox.setVisible(false);
frame.getContentPane().add(comboBox);
JButton btn = new JButton("Populate combo");
btn.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent arg0) {
//populate combo
String[] dir = new String[5];
for(int i = 0; i < dir.length; i++) { dir[i] = "String "+ i;}
comboBox.setModel(new DefaultComboBoxModel<>(dir));
comboBox.setVisible(true);
btn.setEnabled(false); //disable button
}
});
btn.setBounds(23, 68, 89, 23);
frame.getContentPane().add(btn);

EDIT implementation using a layout manager :
private void initialize() {
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JComboBox<String> comboBox = new JComboBox<>();
comboBox.setVisible(false);
frame.add(comboBox, BorderLayout.SOUTH); //using BorderLayout which is the default
JButton btn = new JButton("Populate combo");
btn.setPreferredSize(new Dimension(150,35));
btn.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent arg0) {
//populate combo
String[] dir = new String[5];
for(int i = 0; i < dir.length; i++) { dir[i] = "String "+ i;}
comboBox.setModel(new DefaultComboBoxModel<>(dir));
comboBox.setVisible(true);
btn.setEnabled(false); //disable button
frame.pack(); //resize fram to fit the preferred size and layouts
}
});
frame.getContentPane().add(btn, BorderLayout.NORTH);
frame.pack();
frame.setVisible(true);
}
My problem is that I have a class that when the user types out the text displayed dispose() is called, which works the first time but if you don't close the program and open it again, dispose() is called, but doesn't do anything which breaks the program.

your text field is static so he will have only one instance across the application.
so in the method getIntroTxtField() you have if statement that says :
if (introTxtField == null)
in the first time this condition is true but when you create the new instance this condition is false because the instance of the static field is all ready created in the first and you are adding the key listener inside the condition
so the action listener will be added only in the first creation.
if you need to keep the static because you need in other class you need to remove the == null
protected JTextField getInputTxtField() {
inputTxtField = null;
{
inputTxtField = new JTextField();
inputTxtField.setHorizontalAlignment(SwingConstants.CENTER);
inputTxtField.addKeyListener(new KeyAdapter() {
#Override
public void keyReleased(KeyEvent arg0) {
String strField = textField.getText();
char key = arg0.getKeyChar();
int length = strField.length();
if (Character.toLowerCase(strField.charAt(0)) == Character.toLowerCase(key)) {
inputTxtField.setText(" ");
textField.setText(strField.substring(1));
System.out.println(length);
System.out.println(strField);
if (length - 1 <= 0) {
dispose();
}
} else {
inputTxtField.setText(" ");
}
}
});
inputTxtField.setBounds(56, 177, 314, 40);
inputTxtField.setColumns(10);
}
return inputTxtField;
}
or remove the static from you field declaration static is used in
shared instace only when you are using only one instace across the
application like sessionFactory or any thing that need to be created
only one time.
you code is a lot to read but i think your problem is that you are calling the dispose() of the wrong object. may you are calling it always for the first object and you are creating a new one, and the dispose of this new dialog will never be call,Check you code may be you are creating many object and the dispose() is not called at all. make sure that you have full control of your objects instance to know if you are diposing the wanted dialog.

existing close statements

Connection connDrink = Connections.sqlConn();
int countDrinks = Connections.count();

for (int j = 0; j < countDrinks; j++) {
String dk = "select DrinkID, Drink from Drinks where DrinkID = " + j + ";";
PreparedStatement pSt = connDrink.prepareStatement(dk);
ResultSet rS = pSt.executeQuery();
System.out.println(rS.getString(2));
int oi = Integer.parseInt(rS.getString(1).toString());
`//`list.add(rS.getString(2).toString(), null);
}
}catch(Exception e){
JOptionPane.showMessageDialog(null, e.getClass().getName() + ": " + e.getMessage());
}
}
});
Always gives java.sql.SQLException: Result Set closed and I cant find where the result set is closed or if there is another error
I don't have enough points to comment, so I'll answer here.
you should try
if(rS.first())// move the cursor to the first row, true if there's a row, false otherwise
System.out.println(rS.getString(2));
i have two jframes in my app, Addnmember.java and Frame1.java
Frame1 is the main Jframe,
i want when someone presses the Add button, the Addmember will be shown, i have done this with this code, and every thing is fine:
AddB.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
frame.dispose();
AddMember addmem = new AddMember();
addmem.setVisible(true);
}
});
But in the new Jframe, i want to come back again when Done Bt is selected, i have done this whit this code:
btnNewButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
//dispose();
Frame1 addmem = new Frame1();
addmem.setVisible(true);

thanks.
As to why your second Frame1 shows no data, I'm not 100% sure, but perhaps it has something to do with your failure to close your database connection. Regardless, it seems wasteful and even potentially dangerous to want to gather the database data twice when you've already obtained it once, and to create your Frame1 GUI twice when you've already created it once.
You should re-design your GUI. The main JFrame GUI should remain visible, and the Frame1 window should be a modal JDialog. As a modal dialog, it will prevent users from being able to interact with the parent JFrame until the dialog is no longer visible.
Note that to get started requires only a few changes:
in Frame1.java
AddB.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
// frame.dispose();
AddMember addmem = new AddMember(Frame1.this); // !!
addmem.setVisible(true);
}
});
in AddMember.java
class AddMember extends JDialog {
public AddMember(JFrame frame) {
super(frame, "", ModalityType.APPLICATION_MODAL);
setTitle("\u0627\u0641\u0632\u0648\u062F\u0646 \u0639\u0636\u0648 \u062C\u062F\u06CC\u062F");
// !! setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
btnNewButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
// dispose();
dispose(); // !!
// !! Frame1 addmem = new Frame1();
// addmem.setVisible(true);
}
});
Also, you'll want to avoid null layouts and setBounds(...) as this will lead to very rigid, hard to debug and improve programs.
I'm creating the app using Eclipse Kepler...I've created 3 database in Eclipse- database, entity and UI. In database, it contains ContactDAO,UserDAO and DBManager(for database connection) . In Entity, it contains Contact and User. In UI, it contains ContactAdd, COntactDetails , ContactList, LoginFrame and MenuFrame JFrames. Now, I'm stuck at ContactList frame... it contains ComboBox and I've tried to run it but I can't get the names... this is the code:
public class ContactList extends JFrame {
private JPanel contentPane;
private JTextField txtSearch;
private JComboBox cbContactNames;
private MenuFrame parentFrame;
private Contact selContact;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
ContactList frame = new ContactList(null);
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the frame.
*/
public ContactList(MenuFrame f) {
this.parentFrame = f;
setTitle("Personal Assistant");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 450, 300);
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
setContentPane(contentPane);
contentPane.setLayout(null);
txtSearch = new JTextField();
txtSearch.setBounds(22, 11, 294, 20);
contentPane.add(txtSearch);
txtSearch.setColumns(10);
JButton btnSearch = new JButton("Search");
btnSearch.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
searchContact();
}
});
btnSearch.setBounds(326, 10, 89, 23);
contentPane.add(btnSearch);
JLabel lblName = new JLabel("Name");
lblName.setBounds(42, 88, 46, 14);
contentPane.add(lblName);
cbContactNames = new JComboBox();
cbContactNames.addItemListener(new ItemListener() {
public void itemStateChanged(ItemEvent e) {
if (e.getStateChange()==ItemEvent.SELECTED)
{
if (cbContactNames.getSelectedIndex()>0){
String name=(String)cbContactNames.getSelectedItem();
selContact=ContactDAO.findContactByName(name); //adjusted
showContact();
}
}
}
});
ArrayList<Contact> ContactList=ContactDAO.getAllContacts();
cbContactNames.addItem("--Select Name--");
for (int i=0; i<ContactList.size(); i++)
{
Contact contact = ContactList.get(i);
cbContactNames.addItem(contact.getName());
}
cbContactNames.setBounds(87, 85, 229, 20);
contentPane.add(cbContactNames);
JButton btnClose = new JButton("Close");
btnClose.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
goBack();
}
});
btnClose.setBounds(158, 203, 89, 23);
contentPane.add(btnClose);
}
private void goBack() {
// TODO Auto-generated method stub
parentFrame.setVisible(true);
this.dispose();
}
private void showContact() {
// TODO Auto-generated method stub
ContactDetails contactdetails=new ContactDetails(this,selContact);
contactdetails.setVisible(true);
this.setVisible(false);
}
private void searchContact() {
String name=txtSearch.getText();
if (name!=null){
selContact=ContactDAO.findContactByName(txtSearch.getText());
}
showContact();
}
}
Then, I have also created the ContactDetails frame that contains the contact details, edit save and close buttons, and Delete label set as Image. The project says when the edit button is clicked, the save button will be visible... I don't know how to do that...Here's my code :
public class ContactDetails extends JFrame {
private JPanel contentPane;
private JTextField txtName;
private JTextField txtMobile;
private JTextField txtHome;
private JTextField txtEmail;
private JButton btnEdit;
private JButton btnSave;
private ContactList parentFrame;

Also, the Save button is tricky for me... It seems that after clicking the Save button, a message should pop up for confirmation that should include (OK) button. When the (ok)button is clicked, Save button will be disabled and Edit button will be enabled again. All Text fields will be disabled. The (Delete Icon button) also needs a prompt box that includes (Yes, no and cancel) buttons. If confirm, contact will be deleted and user will be brought back to the contacts list frame... How should I do it?
Tell me if I have to create another JFrame or DAO...
You need somthing like this for your save button and same for remove button:
int showConfirmDialog = JOptionPane.showConfirmDialog(new JFrame(), "Approve?","Title",JOptionPane.YES_NO_OPTION);
if(showConfirmDialog == JOptionPane.YES_OPTION){
btnSave.setEnabled(false);
btnEdit.setEnabled(true);
txtName.setEnabled(false);
//other fields
} else {
//If no or cancel actions
}
Read tutorial for dialogs.
Watch showConfirmDialog(...)
