We Keep Coding

Is there a way to save Strings after the program closes?

I'm trying to make a banking system GUI and I've done well so far but I've run into quite the roadblock. I want to be able to log in, but only if you've previously created an account, but I'm not sure if it's even possible to run my create account class and save the information received for future use since the program will close. I assume it's not possible as I'd need a place to store the username and password for future use, such as a server or something, but I thought I'd ask to see if maybe there was something I could do with an array or something. (P.S. I know I shouldn't use .setLayout(null) but this is just a fun first solo coding project I'm trying to do and I don't understand what people say about it so I'll learn about it later)
Here is my code so far:

GUI become's small whenever I make it visible

I've been making an app with java swing and JavaFX and didn't run into a problem until now. Whenever I set the guis visibility to true, the GUI becomes very small, when it should be 1150 px wide, 900 px tall. Does anyone get any ideas?
Main Gui code:
import javax.swing.*;
import java.awt.*;
public class mainGui extends JFrame{
public static JFrame mainScreen = new JFrame("Tamo");
public mainGui() {
JPanel topPanel = new JPanel();
mainScreen.setSize(1150, 900);
mainScreen.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
mainScreen.setResizable(false);
mainScreen.setLayout(new BorderLayout());
topPanel.setBackground(new Color(226, 230, 204));
topPanel.setPreferredSize(new Dimension(1150, 100));
mainScreen.add(topPanel, BorderLayout.NORTH);
ImageIcon icon = new ImageIcon("C:\\Users\\uname\\Desktop\\TamoDienynas\\pngs\\tamo.png");
mainScreen.setIconImage(icon.getImage());
mainScreen.setVisible(false);
}
public static void main(String[] args) {
new mainGui();
}
}
Class which make's the gui visible:
import javax.swing.*;

timer.start();
}
else{
success.setText("Slapyvardis arba slaptažodis nesutampa!");
}
}
public static void main(String[] args) {

Any help would be appreciated!
P.S. I'm using IntelliJ ultimate as the IDE

mainScreen is just a JFrame that does not contain anything. Hence when you make it visible, all you see is the title bar. In order to initialize mainScreen you need to call mainGui constructor. Nonetheless, as Andrew Thompson wrote in his comment, your style of coding a Swing application is very unusual. Consider using a dialog as your login window.
Here is your code that displays mainScreen as I believe you intended. I only changed the ActionListener, in class loginGui, that displays mainGui. I added one line which is indicated with the comment ADDED THIS LINE

Here is how it appears (after logging in).

Java - Unable to open a new frame from ActionListener

I am currently designing a login screen, but I ran into a strange issue. I already designed my GUI with the help of swing, and it was time to make functional buttons. I wanted to test my login button and if it would take me to the frame I want, but it is unable to. I can set a JOptionPane.showMessageDialog for example, which works just fine, but I am unable to open another frame from the button. I tried with New JFrameName().setVisible(true), and also JFrameName test = new JFrameName(); test.setVisible(true);, but the methods show up in red. Here is my code.
package com.edu4java.swing.tutrial3;
import javax.swing.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class LoginView {
public static void main(String[] args) {
JFrame frame = new JFrame("Bus Tour Booking System");
frame.setSize(300, 200);
frame.setResizable(false);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
frame.add(panel);
placeComponents(panel);
frame.setVisible(true);
}
private static void placeComponents(JPanel panel) {
panel.setLayout(null);
JLabel titleLabel = new JLabel("Bus Tour Booking System");
titleLabel.setBounds(70,15,150,25);
panel.add(titleLabel);
JLabel userLabel = new JLabel("Username: ");
userLabel.setBounds(30, 50, 80, 25);
panel.add(userLabel);
JTextField userText = new JTextField(20);
userText.setBounds(120, 50, 130, 25);
panel.add(userText);
JLabel passwordLabel = new JLabel("Password: ");
passwordLabel.setBounds(30, 80, 80, 25);
panel.add(passwordLabel);
JPasswordField passwordText = new JPasswordField(20);
passwordText.setBounds(120, 80, 130, 25);
panel.add(passwordText);
JButton loginButton = new JButton("login");
loginButton.setBounds(100, 125, 80, 25);
panel.add(loginButton);
ActionListener myButtonListener = new MyButtonListener();
loginButton.addActionListener(myButtonListener);
}
private static class MyButtonListener implements ActionListener {
#Override
public void actionPerformed(ActionEvent e) {
//can't access a new frame from here :(
}
}
}
I would be very grateful if someone could help me out, I read a lot on Stackoverflow and Reddit, but just can't find the solution. I am also new to Java, so that doesn't help a lot either :D. Thanks in advance!
P.S. As far as the actual functionality for the login screen, I am going to do that in a later stage.

This is your login class. I put the JFrame frame in the global scope, so you can manipulate it from the ButtonListener method. I also created a SomeFrame class, just to demonstrate the new JFrame that would be created when you click the button. When an action is performed(the button is clicked) a new object of SomeFrame is created. Since SomeFrame extends JFrame we can use the method setVisible() to a SomeFrame object. The SomeFrame frame appears and the LoginView is no longer visible.
import javax.swing.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class LoginView {
public static JFrame frame = new JFrame("Bus Tour Booking System");
public static void main(String[] args) {
frame.setSize(300, 200);
frame.setResizable(false);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
frame.add(panel);
placeComponents(panel);
frame.setVisible(true);
}
private static void placeComponents(JPanel panel) {
panel.setLayout(null);
JLabel titleLabel = new JLabel("Bus Tour Booking System");
titleLabel.setBounds(70,15,150,25);
panel.add(titleLabel);
JLabel userLabel = new JLabel("Username: ");
userLabel.setBounds(30, 50, 80, 25);
panel.add(userLabel);
JTextField userText = new JTextField(20);
userText.setBounds(120, 50, 130, 25);
panel.add(userText);
JLabel passwordLabel = new JLabel("Password: ");
passwordLabel.setBounds(30, 80, 80, 25);
panel.add(passwordLabel);
JPasswordField passwordText = new JPasswordField(20);
passwordText.setBounds(120, 80, 130, 25);
panel.add(passwordText);
JButton loginButton = new JButton("login");
loginButton.setBounds(100, 125, 80, 25);
panel.add(loginButton);
ActionListener myButtonListener = new MyButtonListener();
loginButton.addActionListener(myButtonListener);
}
private static class MyButtonListener implements ActionListener {
#Override
public void actionPerformed(ActionEvent e) {
SomeFrame newFrame = new SomeFrame();
newFrame.setVisible(true);
frame.setVisible(false);
}
}
}
This is the SomeFrame class.
import javax.swing.JFrame;
import javax.swing.JPanel;
public class SomeFrame extends JFrame {
public SomeFrame(){
super("something");
this.setSize(300, 200);
this.setResizable(false);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
this.add(panel);
this.setVisible(true);
}
}

How to manipulate elements of ArrayList<Object> using JList

Hi I'm trying to display an ArrayList of Objects on a Jlist. While displaying the ArrayList, I'm trying to be able to add or delete objects to the ArrayList through the GUI.
1) How can I display the ArrayList objects on the Jlist? 2)How can I delete an object by selecting it on the JList?

There are no syntax errors, however my Jlabel is not added (the buttons work fine). I do not want to change the layout from null, as I want to be able to define the positions of the buttons and labels. Does anyone know why this isn't working?

This question is similar to JLabel won't show with JPanel.setLayout(null). Why?
To answer it here, add a line like this:
startQuestion.setBounds(150, 150, 200, 20);

import javax.swing.*;
import java.awt.*;
import java.awt.Graphics;
public class Test extends JFrame{
private JButton by;
private JButton bn;
JLabel startQuestion;
public Test() {
JPanel p = new JPanel();
by = new JButton("Yes");
bn = new JButton("No");
startQuestion = new JLabel("Would you like to start?");
//p.setLayout(null);
by.setBounds(180, 250, 70, 45);
bn.setBounds(250, 250, 70, 45);
startQuestion.setLocation(195, 240);
p.add(by);
p.add(bn);
add(startQuestion);
add(p);
setDefaultCloseOperation(3);
setSize(500, 500);
setVisible(true);
}
public static void main(String...args) {
new Test();
}
}
Note:
you need to comment setlayout(null);
