I got "error:cannot find symbol" for the JButton inside a frame outside of a JTabbedPane [duplicate]

This question already has answers here:
What does a "Cannot find symbol" or "Cannot resolve symbol" error mean?
(18 answers)
Closed 4 years ago.
So I have a frame, inside the frame there are tabs. I tried to put Jbutton outside of the tab but it wouldn't recognize my Jbutton. I keep on getting
error: Cant find symbol.
I don't understand why that happened. Would someone explain?

First of all, your code is a mess. Unreadable. And you are violating a whole lot of style rules, which is going to discourage anyone from trying to read your code.
(And that kind of makes asking people to help you problematic ..... doesn't it!)
Your "Cannot find symbol" errors seem to have a common explanation. Here's the first one:
menu.java:544: error: cannot find symbol
p2A1.add(MB); p2A1.add(MBp1); p2A1.add(tf11); p2A1.add(MBm1);
^
symbol: variable MB
location: class menu
When I trawl through the code, I cannot find any declaration for a variable called MB. Or mb. Or anything resembling this.
The other errors are similar.
Basically, you have either dumped in a bunch of statements that refer to things that are not declared ... or you have somehow managed to lose the declarations.
I don't think there is much we can do you help you with your code. It is ... incomprehensible.
However, if you need to understand the various things that can cause the Java compiler to produce that error message, read this:
What does a "Cannot find symbol" compilation error mean?

Finding Area within an action event

I am writing a program for class, and I have about all of it done but one part that is really confusing me.
I have to create a system for flooring that a person can choose the floor type, enter their length and width of their floor and it calculates and produces a order summary.
Now, I am able to get all of this but the calculations correct (and I haven't even started on the database connection because of it.)
My professor is extremely vague in her directions and even the answers to her questions, so as a last ditch effort I thought I would try here.
I cannot for the life of me figure it out so ANY help is greatly appreciated.

I can see two basic things that needs to be changed:
a. this does not compile (floorSize should be double)
String floorSize;
double floorLength = Double.parseDouble(length.getText());
double floorWidth = Double.parseDouble(width.getText());
floorSize = floorLength * floorWidth;
b. The calculation of floorSize should not be triggered by ChangeListener (which causes the calculation to be done before values are entered).
Use "Order Summary" JButton to trigger the calculation.
Here is a working version of the code. See my comments:

Having prob with my "Display Data Button"

Try running my program. Press Add Subject (fill the data). Then Display. Then Add another subject. Then Display.

I do not know where to find the reason why my program makes this error.

I found your problem it's here addButton.addActionListener(). You always add a new ActionListener to your button instance, because of that, every time you push addSubject button you also add a new Listener to addButton. Don't do that in the future, add your Listeners to Components, in method of component construction.

JButton exits JPanel

I have multiple cancel, ok, and save buttons. When the user clicks one of these buttons, I need it to exit the JPanel, but not the whole program. I have tried multiple times and everything I do it exits the whole program. My code is below. I know there is a lot of stuff on my code and it can get confusing. Thanks in advance.

I have tried multiple times and everything I do it exits the whole program.
I don't see you code for closing the dialog so I can't guess what you might be doing wrong.
In your ActionListener you would invoke the dispose method on the dialog. The code would be something like:
JButton button = (JButton)event.getSource();
Window dialog = SwingUtilities.windowForComponent( button );
dialog.dispose();
A different approach might be to use a JOptionPane, then you don't need to code your own ActionListeners. You can easily add a panel to an option pane. The code below shows two approaches:
import java.awt.*;
import javax.swing.*;
public class OptionPanePanel
{
private static void createAndShowUI()
{
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLocationRelativeTo( null );
frame.setVisible( true );
// Build a custom panel
JPanel panel = new JPanel( new GridLayout(2, 2) );
panel.add( new JLabel("First Name") );
JTextField firstName = new JTextField(10);
// firstName.addAncestorListener( new RequestFocusListener(false) );
panel.add( firstName );
panel.add( new JLabel("Last Name") );
JTextField lastName = new JTextField(10);
panel.add( lastName );
int result = JOptionPane.showConfirmDialog(
null, // use your JFrame here
panel,
"Enter Name",
JOptionPane.YES_NO_OPTION,
JOptionPane.PLAIN_MESSAGE);
if(result == JOptionPane.YES_OPTION)
{
System.out.println(firstName.getText() + " : " + lastName.getText());
}
else
{
System.out.println("Canceled");
}
// Let Option Pane build the panel for you
Object[] msg = {"First Name:", firstName, "Last Name:", lastName};
result = JOptionPane.showConfirmDialog(
frame,
msg,
"Enter Name...",
JOptionPane.OK_CANCEL_OPTION,
JOptionPane.PLAIN_MESSAGE);
if (result == JOptionPane.YES_OPTION)
{
System.out.println(firstName.getText() + " : " + lastName.getText());
}
else
{
System.out.println("Canceled");
}
}
public static void main(String[] args)
{
EventQueue.invokeLater(new Runnable()
{
public void run()
{
createAndShowUI();
}
});
}
}
One problem with this approach is that focus will be on the OK button instead of the text field. To get around this you can use the RequestFocusListener found in Dialog Focus.

new Database();
calls an empty Constructor, because you dont define none.
Change public void Database() {} to public Database()
Also, you have to eliminate Database Dab = new Database(); from your Constructor and change the Line Dab.setSize(800,300); to setSize(800,300);
Your Code will work when you make this changes but you should really work on your Programming Style and Code Formatting.
