Question

I have a JFileChooser and Im able to print the Absolute Path in console.
I need to show the FilePath in a Text field as soon as the User selects the file.

Below is the code please let me know how to do it.

        public void actionPerformed(ActionEvent ae) {

        JFileChooser fileChooser = new JFileChooser();
        int showOpenDialog = fileChooser.showOpenDialog(frame);

        if (showOpenDialog != JFileChooser.APPROVE_OPTION) return;

Please let me know if you need any other details.

Answer 1

You need to listen to the changes that occur when using the JFileChooser, see this snipet of code:

JFileChooser chooser = new JFileChooser();

// Add listener on chooser to detect changes to selected file
chooser.addPropertyChangeListener(new PropertyChangeListener() {
    public void propertyChange(PropertyChangeEvent evt) {
        if (JFileChooser.SELECTED_FILE_CHANGED_PROPERTY
                .equals(evt.getPropertyName())) {
            JFileChooser chooser = (JFileChooser)evt.getSource();
            File oldFile = (File)evt.getOldValue();
            File newFile = (File)evt.getNewValue();

            // The selected file should always be the same as newFile
            File curFile = chooser.getSelectedFile();
        } else if (JFileChooser.SELECTED_FILES_CHANGED_PROPERTY.equals(
                evt.getPropertyName())) {
            JFileChooser chooser = (JFileChooser)evt.getSource();
            File[] oldFiles = (File[])evt.getOldValue();
            File[] newFiles = (File[])evt.getNewValue();

            // Get list of selected files
            // The selected files should always be the same as newFiles
            File[] files = chooser.getSelectedFiles();
        }
    }
}) ;

All you need to do inside the first condition is set the value of your textfield to match the new selected filename. See this example:

yourTextfield.setText(chooser.getSelectedFile().getName());

Or just

yourTextfield.setText(curFile.getName());

It is the method getName() from class File that will give you what you need.
Help your self from de API docs to see what each method does.
