JAVA jframe.remove(panel) doesn't work as expected

I have a Jframe with two panels and i am trying to change the panels/views using jmenu items.
The first panel adds data to a database. User can then switch to the view panel by clicking the JMenuBarItem.
The Second panel fetches data from the database and displays the results in a JTable.
Everything works fine but when i switch back and forth to the second panel it adds another panel instead of removing it/replacing it. See linked images below to better understand
First Panel
Second Panel
Second Panel after switching back and forth

The mistake you made is that you create a new JTable every time you open the viewpanel. You not only create a new one, you add it to your view-JPanel. This is why you get the weird behaviour.
This code snippet fixes your problem. I just added the removeAll() method call to the add-JPanel ActionListener. When the add-JPanel is opened, the old JTable is removed from the view-JPanel. I had to comment out your database interactions.
// ...
// ...
// ...
add.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent ae)
{
if (viewpanel.isShowing())
{
remove(viewpanel);
/*
* I basically just added this one line.
* Since you want to make a fresh query after
* you come back to the viewpanel, we can delete
* all the elements (which is only the JTable).
*/
viewpanel.removeAll();
add(addpanel);
}
revalidate();
repaint();
}
});
view.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent ae)
{
java.util.List<String[]> datalist = new ArrayList<>();
String[] columnNames = {"Emp ID", "Emp Name", "Department",
"Basic Pay", "House Allowance", "Payee", "NHIF", "NSSF",
"Pension", "NetPay"};
try
{
// String query = "SELECT * FROM payroll";
// Class.forName("com.mysql.jdbc.Driver");
// Connection con = DriverManager.getConnection(host, username,
// password);
// Statement st = con.prepareStatement(query);
// ResultSet rs = st.executeQuery(query);
String[] results = {"a", "b", "c", "d", "e", "f", "g", "h",
"i", "j"};
datalist.add(results);
// con.close();
String[][] data = new String[datalist.size()][];
data = datalist.toArray(data);
JTable table = new JTable(data, columnNames);
JScrollPane sp = new JScrollPane(table);
viewpanel.add(sp);
}
catch (Exception ex)
{
ex.printStackTrace();
}
if (addpanel.isShowing())
{
remove(addpanel);
add(viewpanel);
}
else if (viewpanel.isShowing())

The solution on top is not the only one of course. I don't know where you wanna go with this UI, but you can just remove the contents of the table and refill them as soon as you open the view-JPanel again.
Another solution would be to remove the JTable specifically (but in this case you probably need to have it as a field, because you create the table in a block that you can't reference from your add.addActionListener-Block)
The third solution would be to add a boolean flag, that checks if the table has been loaded and only create a new JTable, if it hasn't.

The problem here is the JLabel and JTextField(nom, prenom)don't appear in the form in order to insert or select from database. Have any idea how can i correct it please. Thank you

p2.add(l1);
p2.add(tf1);
p2.add(l2);
p2.add(tf2);
These above fields are added in both p1(Tab1) and p2(Tab2) Panels.
Thats why its not showing.
You must create seperate controls for both p1 and p2 panels. Don't reuse same controls in two panels.
For example:
l7 = new JLabel("Normal");
p2.add(l7);

JtextField Settext and static type

I have a Swing Form (Java). In this form I have field, for example Name1. I initialize it so:
private JTextField Name1;
In this code i'm adding JTextField Name1 into my Form:
tabbedPane.addTab("T6", null, panel, "T6");
panel.setLayout(null);
Name1.setBounds(73, 11, 674, 20);
panel.add(Name1);
Additionaly I have Button1 on my form. The event in this button is changing the value of Name1. Its work normaly.
Moreover I have a Button 2 that hiding the Tab with Name1:
tabbedPane.remove(1);
tabbedPane.repaint();
tabbedPane.revalidate();
frame.repaint();
frame.revalidate();
(And, of course, I turn on my tabpane again after this)
After all that, by the pressing the Button 4 I want to change the vlue of Name1 to some text.
But it doesn't work!!!!!! SetTex doesnt work. The field is empty.
So, if I change the Name1 declaration from
private JTextField Name1;
to
static JTextField Name1;
Yes, it works. BUT! Then I can't change the value of Name1 by using
Name1.Settext("Example");
What i have to do to make Name1 available after Button 4 pressed and changable ????
The all code is:

Java application with multiple jframe-threads

Hello all I am building a java application where i want to select a users from a list of users and create a new JFrame to chat with(for example a new user-to-user chatbox). I have created the new JFrame into a thread i called it ChatGUI.
I am working with Smack so each of my ChatGUI object should have a MessageListener. When i exit a chatGUI thread it should delete everyting the thread created(for example the MessegeListener) and exit without interrupting any of the other threads(with their own MessegeListeners).

Problem: For now i can create a new ChatGUI for each user but when i click exit in any of the created chatGUI-threads it closes the main process and all other chatGUIs.
Apologize for bad English.

I found the solution:
Since I am using Smack 3.2.2 it does not have the capability to stop a Chat.
My JFrame exited well after using newFrame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); instead of using newFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

Change Title of JFrame in my program

I am having trouble with one part of my code. I have been working for so long on this and I am exhausted and missing something easy. I need to have a text box to enter a new title for the JFrame, a button that says "Set New Name" and an "Exit Button.
Can someone look at this code and give me some info so I can go to bed.
Thank you
//Good One

Let's start with this (which I assume is where you create the details)...
private void optionsTab() {
optionsPanel = new JPanel(new FlowLayout());
//optionsPanel.setLayout(null);
JLabel labelOptions = new JLabel("Change Company Name:");
labelOptions.setBounds(120, 10, 150, 20);
optionsPanel.add(labelOptions);
final JTextField newTitle = new JTextField("Some Title");
newTitle.setBounds(80, 40, 225, 20);
optionsPanel.add(newTitle);
final JTextField myTitle = new JTextField("My Title...");
myTitle.setBounds(80, 40, 225, 20);
myTitle.add(labelOptions);
JButton newName = new JButton("Set New Name");
newName.setBounds(60, 80, 150, 20);
//newName.addActionListener(this);
optionsPanel.add(newName);
optionsPanel.add(createExitButton());
}
The newTitle field is a local variable, so once the method exists, you will not be able to access the field (easily)...
You seem to have tried adding a actionListener to the newName button, which isn't a bad idea, but because you can't actually access the newTitle field, isn't going to help...
The use of setBounds is not only ill advised, but probably won't result in the results you are expecting, because the optionsPane is under the control a layout manager...
And while I was digging around, I noticed this if (errors != "") {...This is not how String comparison is done in Java. This is comparing the memory references of both Strings which will never be true, instead you should if (!"".equals(errors)) {...
But back to the problem at hand...
You are really close to having a solution. You could make the newTitle field a class instance variable, which would allow you to access the field within other parts of your program, but because you've made it final, there's something else you can try...
You can use an anonymous inner class instead...
newName.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
setTitle(newTitle.getText());
}
});
Which should get a good nights sleep :D

It is a little unclear what you want, but if I understand you right you want the JButton newName to set the title of the JFrame to the text in some textbox?
In that case you would write
setTitle(someTextbox.getText());
inside the function of the button.

First, you need to create a JTextField that has public access. Then, create a JButton that implements ActionListener. After that you must implement the abstract method actionPerformed() in the JButton Subclass. Then in the run method say JFrame.setTitle(JTextfield.getText()).
Subclass Method:
public class main extends JFrame{
// Construct and setVisible()
}
class textfield extends JTextField{
// create field then add to JFrame
}
class button extends JButton implements ActionListener{
// create button
public void actionPerformed(ActionEvent e){
main.setTitle(textfield.getText());
}
Instance Method:
public class main implements ActionListener{
JFrame frame = new JFrame();
JPanel panel = new JPanel();
JTextField field = new JTextField();
JButton button = new JButtone();
button.addActionListener(this);
panel.add(field);
panel.add(button);
frame.add(panel);
public void actionPerformed(ActionEvent e){
frame.setTitle(field.getText);
}
}

Try This
private void optionsTab() {
optionsPanel = new JPanel(new FlowLayout());
// optionsPanel.setLayout(null);
JLabel labelOptions = new JLabel("Change Company Name:");
labelOptions.setBounds(120, 10, 150, 20);
optionsPanel.add(labelOptions);
final JTextField newTitle = new JTextField("Some Title");
newTitle.setBounds(80, 40, 225, 20);
optionsPanel.add(newTitle);
final JTextField myTitle = new JTextField("My Title...");
myTitle.setBounds(80, 40, 225, 20);
myTitle.add(labelOptions);
JButton newName = new JButton("Set New Name");
newName.setBounds(60, 80, 150, 20);
newName.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
setTitle(newTitle.getText());
}
});
// newName.addActionListener(this);
optionsPanel.add(newName);
optionsPanel.add(createExitButton());
}
