How to scan a list of files in current directory using JFileChooser ??

I need to parse the files in the current directory into a menu that displays either txt or java source files to be displayed in a text area.

I'm getting several these errors:

JFileChooser chooser = new JFileChooser(getCurrentDirectory());

import java.util.Scanner;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.filechooser.*;
import java.io.*;
 
public class ScrollText extends JFrame {
 
public ScrollText() {

setTitle("ScrollText");
setSize(600, 400);
setLayout(new BorderLayout());

JTextArea textArea = new JTextArea();
JScrollPane scrollPane = new JScrollPane(textArea);
JMenuBar menuBar = new JMenuBar();
JMenu menu = new JMenu("<html><span style=\"font-size:130%;\">Display Local File</span></html>");
menu.setBorder(BorderFactory.createEtchedBorder());

menuBar.add(menu);
add(menuBar, BorderLayout.NORTH);

File currentDirectory = JFileChooser.getCurrentDirectory();

JFileChooser chooser = new JFileChooser(currentDirectory);
    
    
scrollPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED);
scrollPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);

scrollPane.setBounds(0, 0, 522, 322);
 
add(scrollPane, BorderLayout.CENTER);

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
}

public static void main(String[] args) {

new ScrollText();
}

public boolean accept(File f) {
    
    if (f.isDirectory())
return false;
    
 
    String s = f.getName();
    
    int i = s.lastIndexOf('.');
 
    if (i > 0 &&  i < s.length() - 1) {

String extension = s.substring(i + 1).toLowerCase();

if ("txt".equals(extension) || "java".equals(extension)) 
        return true;
else 
    return false;
}
 
    return false;
}
 
} // end ScrollText

This one says the method getCurrentDirectory() isn't found. With this syntax the compiler is looking in the current class and if you didn't write it, it ain't there.

And this one says the method is actually on JFileChooser, but you need to create an instance to call the method.

Try this and let us know if it does what you expect ...

Well, I tried EXACTLY what you recommended:

import javax.swing.*;

JFileChooser fc = new JFileChooser();
System.out.println(fc.getCurrentDirectory());

I get:

Cannot find symbol
Symbol: method getCurrentDirectory
Class: JFileChooser

In fact I can't use a single solitary JFileChooser property nor method without the "cannot find symbol" compiler error every time

So this "JFileChooser" class you're using: is it the javax.swing.JFileChooser class, or is it a JFileChooser class you wrote yourself and put into your default (not in a package) directory? Your error message suggests the latter.

NO, consider this:

/*
* Stuff.java
*
* Created on January 22, 2007, 3:54 PM
*
* To change this template, choose Tools | Template Manager
* and open the template in the editor.
*/
import javax.swing.*;
/**
*
* @author ppowell-c
*/
public class Stuff {
/** Creates a new instance of Stuff */
public Stuff() {
}

public static void main(String[] args) {
JFileChooser chooser = new JFileChooser();
chooser.setDialogTitle("Blah");
}
}

Also produces "cannot find symbol" error. And I'm importing all of javax.swing.*

But if you had a class in the default package named JFileChooser then the compiler would use that regardless of what you imported from named packages. Look (or look again, if you didn't look before) to see if you did that.

It compiles fine for me...

One quick way to tell, if there is another JFileChooser in conflict, is to not use import. Use the fully qualified name, and see if it works.

That was exactly it! Embedded in a hidden subdirectory to boot!
