JTextfield array, retrieve name and text

Question

I have an array of JTextField and when a JTextField is modified I want to have the name of the JTextField and the text.

while ((line = bufferedReader.readLine()) != null) { // 1 by 1 line of file
    if (f == 6) {
        g++;
        f = 0;
    }
    tableauDonnee[g][f] = line;
    fields[g][f] = new JTextField(tableauDonnee[g][f]);
    fields[g][f].setName(String.valueOf(g + etf));
    fields[g][f].setBounds(positionY, positionX, 160, 40);
    pan.add(fields[g][f]);
    positionY = positionY + 180;
    f++;

I can do that before add JTextField to panel

fields[g][f].addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent event) {
        textfield = fields[g][f].getText();
        nameTextfield = fields[g][f].getName();
    }
});

But it will not work because values of g and f are not good.

I'm stuck and don't know what to do.

You can get the source of the event (ie, the text field where you pressed the Enter key) from the ActionEvent:

public void actionPerformed(ActionEvent event) 
{
    JTextField textField = (JTextField)event.getSource();
    ...
}

Also, why are you use a 2D array of text fields.

I would suggest a JTable would be the better components to use. Read the section from the Swing tutorial on How to Use Tables for more information.

If i use it it return me that javax.swing.JTextField[5,750,110,160x40,layout=javax.swing.plaf.basic.BasicTextUI$UpdateHandler,alignmentX=0.0,alignmentY=0.0,border=javax.swing.plaf.BorderUIResource$CompoundBorderUIResource@4fa1d375,flags=296,maximumSize=,minimumSize=,preferredSize=,caretColor=sun.swing.PrintColorUIResource[r=51,g=51,b=51],disabledTextColor=javax.swing.plaf.ColorUIResource[r=184,g=207,b=229],editable=true,margin=javax.swing.plaf.InsetsUIResource[top=0,left=0,bottom=0,right=0],sel etc. Where can i retrieve the name and text. By the way textfield is a string not a jtextfield – lefebvre remy Dec 03 '19 at 19:18
