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?

I'm new in Java programming so that's why I'm here seeking your kind help stackoverflowers.
I have this problem which I could not find the solution on internet, I hope someone could inform me where is my mistake and how can I fix it.
My problem is that when I try to insert the data, everything goes fine, the window opens, I can insert the data, button looks just fine.
But it gives me this message
java.sql.SQLIntegrityConstraintViolationException: Column 'prenom' cannot be null
Which I assume was a problem with php mySQL, then I changed all variables to NULL, activating the button "Null" for all of them.
It then WORKED, but all informations were saved as "null" in my database, which didn't really solve my problem.
My goal is to insert data (name, lastname, phone, email) into a data base (php mySQL) through eclipse. I did a program which I'm obliged to use window builder to insert that data, so graphical user interface MUST be used
What I expect to happen is to save data normally. Like, name = Mike, lastname = Tyson, phone = +55555, email = mtyson#gmail.com
And it shows in my database, not null message.
Thank you everyone

I've been having trouble with exporting my GUI project from Eclipse Oxygen. At first I tried exporting my project by going to export>Runnable Jar File>Main Class, but when I try and open my program nothing shows up. Then I tried opening the GUI inside its own class by specifying a Main method in there, and I keep getting the error that I put in the title. Any help would be appreciated. I'll post both of my classes here.
Also I used WindowBuilder plugin to build my GUI.

Turns out that winrar does not like runnable jar files. I had tried Right Clicking the file and running it as a java application SE binary, but it would not work. So after #Adam Horvath mentioned that it worked for him I set the exported jar to default java jar and it opened up just fine.
This question already has answers here:
how to change UI depending on combo box selection
(1 answer)
Positioning component inside card layout
(1 answer)
Closed 5 years ago.
I am trying to change between card panels using the Jcombobox "Expenses". Can someone tell me what I'm doing wrong? I get the panels to appear properly, but when I see the Expenses j tabbed pane, the first card is shown. Once I try to switch between them, the console gets filled with errors. I noticed that all cards are showing at the same time, but they are overlapping.
1)How do I get only one card (panels) showing at once?
2)How do I get the JComboBox to switch between cards(panels)?

Seriously? You're setting the cards layout to CardLayout, and then immediatly setting it again to null. And then you get a NullPointerException when you try to use the cards "layout" -- no surprise!
I am trying to open a new JDialog when the "Register" Button is clicked..
But I am unable to make the JDialog modal..
I have tried setModal(true) and also setModalityType(ModalityType.DOCUMENT_MODAL);
But no luck..(I am using Eclipse's WindowBuilder plugin)
P.S: I am new to JAVA..
Here is my code...

Try making the dialog modal BEFORE you try and make it visible. You can't change the modal state once the dialog is made visible...
JDialog jd=new JDialog(loginpage.this,"User Registration");
jd.setModal(true);
jd.setLayout(null); // THIS IS A BAD IDEA //
jd.setLocationRelativeTo(null);
// This is somewhat pointless, you've set relative location, but know overridden it...
// You should also be relying on the layout manager and pack to determine the size...
jd.setBounds(400,300, 479, 329);
jd.setResizable(false);
setLocationRelativeTo(loginpage.this);
// Add you other components
jd.setVisible(true);
This is kinda a silly question, but I'm beggining with java swing and have been doing kinda great, but I really can't make a JTable appear in my form, so far a blank square appears but no columns at all, here's a snippet:
DefaultTableModel modelo = new DefaultTableModel();
modelo.setColumnCount(1);
tblTrans = new JTable(modelo);
modelo.addColumn("Prueba");
tblTrans.revalidate();
tblTrans.setBounds(316, 47, 248, 243);
contentPane.add(tblTrans);

What I want to accomplish is to add a column for each "Estado" given, the program is about non deterministic automata, and a row for each "Lenguaje" given so I can make the transition matrix, I do know how to make this each time the buttons are pressed, but it appears like the column is being added but it's not visible at all, just a blank square.
Corrections suggested:
DefaultTableModel modelo = new DefaultTableModel();
modelo.setColumnCount(1);
tblTrans = new JTable(modelo);
panel.add(tblTrans);
panel.setBounds(316, 47, 248, 243);
modelo.addColumn("Test");
tblTrans.revalidate();
contentPane.add(panel);
I was right about the scroll pane. This is working for me:
DefaultTableModel modelo = new DefaultTableModel();
modelo.setColumnCount(1);
modelo.addColumn("Prueba");
tblTrans = new JTable(modelo);
JScrollPane sPane = new JScrollPane(tblTrans);
sPane.setBounds(316, 47, 248, 243);
contentPane.add(sPane);
