Why can't I setText this jTextField?

Question

So I have been writting this code, but for 2 days I haven't been able to figure out the problem. This is the fragment of the code where the problem is:

public void updatee(String gatavs){
    lauks.setText(gatavs);
    System.out.println(gatavs+"?!");
}
public void setup(int garums, String vards){

    labul.setText(vards);
    int i=1;
    String a="-";
    while(i<=garums){
        lauks.setText(a);
        a=a+"-";
        i++;
    }
}

This is in a JFrame class. At the start I call the method setup from another class and it sets the text in lauks textfield just fine, but later when i call the method updatee it doesn't settext lauks to the other string. I even put the println so i could check if it has the string gatavs, and it printed to the console just fine. What could be the problem here?

EDIT:Here is the full JFrame class:

    }

        while (k < word.length()) {
            char ch = word.charAt(k);
            if (ch == b) {
                gatavs = gatavs.substring(0, k) + ch + gatavs.substring(k + 1);
            }
            k++;
        }
        j.updatee(gatavs);
        System.out.println(gatavs);

    }
}

Answer 1

You have a lot of design issues and you should consider starting your project from scratch. I am not an expert in Swing, but you might wanna consider something like this:

Start with a main class that will be used only for starting up your program and making some ground level configurations:

public class WPMAIN {

    // Entry point of your program (should be one and only)
    public static void main(String[] args) {
        // Creation of the frame and setting it visible
        WPFrame frame = new WPFrame();
        frame.setVisible(true);
    }

}

Then in the JFrame, try to minimize redundant code. If you have tons of buttons, that do the same thing, but just a little bit differently, make a method that contains all the code that remains the same:

import java.awt.Color;
import java.awt.Dimension;
import java.awt.Insets;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.GroupLayout;
import javax.swing.GroupLayout.Alignment;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.LayoutStyle.ComponentPlacement;
import javax.swing.border.EmptyBorder;
import javax.swing.border.LineBorder;

@SuppressWarnings("serial")
public class WPFrame extends JFrame {

    private JPanel contentPane;
    private JButton A;
    private JButton B;

    public WPFrame() {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setBounds(100, 100, 450, 300);
        contentPane = new JPanel();
        contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
        setContentPane(contentPane);

        A = new JButton("A");
        setupButton(A);
        B = new JButton("B");
        setupButton(B);

        GroupLayout gl_contentPane = new GroupLayout(contentPane);
        gl_contentPane.setHorizontalGroup(gl_contentPane.createParallelGroup(Alignment.LEADING).addGroup(
                gl_contentPane.createSequentialGroup().addComponent(A, GroupLayout.PREFERRED_SIZE, 25, GroupLayout.PREFERRED_SIZE).addPreferredGap(ComponentPlacement.RELATED)
                        .addComponent(B, GroupLayout.PREFERRED_SIZE, GroupLayout.DEFAULT_SIZE, GroupLayout.PREFERRED_SIZE).addContainerGap(237, Short.MAX_VALUE)));
        gl_contentPane.setVerticalGroup(gl_contentPane.createParallelGroup(Alignment.LEADING).addGroup(
                gl_contentPane
                        .createSequentialGroup()
                        .addGroup(
                                gl_contentPane.createParallelGroup(Alignment.BASELINE).addComponent(A, GroupLayout.PREFERRED_SIZE, GroupLayout.DEFAULT_SIZE, GroupLayout.PREFERRED_SIZE)
                                        .addComponent(B, GroupLayout.PREFERRED_SIZE, GroupLayout.DEFAULT_SIZE, GroupLayout.PREFERRED_SIZE)).addContainerGap(227, Short.MAX_VALUE)));
        contentPane.setLayout(gl_contentPane);
    }

    public void setupButton(final JButton init) {
        init.setMargin(new Insets(2, 2, 2, 2));
        init.setSize(25, 25);
        init.setPreferredSize(new Dimension(25, 25));
        init.setMinimumSize(new Dimension(25, 25));
        init.setMaximumSize(new Dimension(25, 25));
        init.setBorder(new LineBorder(new Color(0, 0, 0)));

        // Action listener that is separate for each button you create,
        // but like this you control all the buttons' actions at once
        init.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                System.out.println(init.getText());
                JOptionPane.showMessageDialog(contentPane, "You pressed " + init.getText());
            }
        });
    }
}

Note that this is only a suggestion, I don't claim this is the right way to do it, or the best way to do it... Just that it will give you more control with the code you are writing. You can take these classes, and run them to see how it works. It's reasonably simple and maybe you can try to build on it.

Answer 2

Looking into your source code, it seems like you have a lot of issues mixed together which does not only concern the setup() method (note that I can't even see a call to this method in the main OP):

• The major one for me is your parbaud1 signature and body, where you are creating an instance of JFrame (your own frame implementation) and calling the parbaud1 method on that instance object:

  JFrame j = new JFrame();
  //...
  jFrame.updatee(gatavs);
  

This will almost result on a new object created each time one of you action listeners delegate the event handling logic to this method having no effective result on your main frame since your code is applied on a different object from you visual one.

The soltution would then be to change the method signature to hold a JFrame instance, and pass the current JFrame instance in each call in your action listener logic:

public void parbaud1(JFrame jFrame, char b, String word, String gatavs)
{
  int k = 0;
  //    JFrame j = new JFrame();
  while (k < word.length())
  {
    char ch = word.charAt(k);
    if (ch == b)
    {
      gatavs = gatavs.substring(0, k) + ch + gatavs.substring(k + 1);
    }
    k++;
  }
  jFrame.updatee(gatavs); // Update the parmaeter argument and don't create a new one
  System.out.println(gatavs);
}

Then calling it as follows:

private void aActionPerformed(java.awt.event.ActionEvent evt)
{
  String word = labul.getText();
  String gatavs = lauks.getText();
  char b = 'A';
  par.parbaud1(this, b, word, gatavs); // Use the current JFrame instance
}

• The second issue may be that no text is appended to the gatavs object since the main condition k < word.length() is never reached, why?.

Simply said because following the method chaining the word will reference the labul object which is never filled with text (word.lenght() will be always 0), so you may need to initialize that label with some text following your needs.

Fixing both upper listing would help wordarounding the updatee method issue, but you still will fall into others reading your code such as StringOutOBoundExceptions, e.g:

gatavs = gatavs.substring(0, k) + ch + gatavs.substring(k + 1); // If the first character is matched gatavs.substring(k+1) will fail because you gatavs String which value come from `lauks` is already empty because the text field is not even editable.

Here you can a working copy of your code.
