JFileChooser/FileFilter{Resolved}

Anyone know what i might be doing wrong. I can see that when jfc.showOpenDialog(jf); is called all of the files within the current directory are being scanned cause i can see them flying through the dos window, but when i change the extension in the FileDialog the files that come up within the JFileChooser aren't being filtered.

Code:

---

openfile.addActionListener(new ActionListener(){
  public void actionPerformed(ActionEvent evt){
    class JavaFilter extends javax.swing.filechooser.FileFilter{
      public boolean accept(File file){
      String filename = file.getName();
      String extension = filename.substring(0, filename.length());
      System.out.println(extension);
      if(extension.equals(".java")){
        return true;
      }
        return false;
      }
      public String getDescription() {
        return ".java Files";
      }
      }
      JFileChooser jfc = new JFileChooser();
      jfc.setFileFilter(new JavaFilter());
      jfc.showOpenDialog(jf);
  }
  });

I don't know if this will help, but this is the Filter class I used for my Text Editor, and it works...

Code:

---

import java.io.File;

public class TextFileFilter extends javax.swing.filechooser.FileFilter
{
        public boolean accept(File f)
        {
                // if its a directory show it
                if (f.isDirectory())
                        return true;
               
                //Get the file extention
                String extention = getExtention(f);
                //Check to see if the extention is equal to "txt" or "text"
                if ((extention.equals("txt")) || (extention.equals("text")))
                        return true;
               
                return false;
        }
       
        public String getDescription()
        {
                return "Text files";
        }
       
        /**
          Method to get the extention of the file, in lowercase
        */
       
        private String getExtention(File f)
        {
                String s = f.getName();
                int i = s.lastIndexOf('.');
                if (i > 0 && i < s.length() - 1)
                        return s.substring(i+1).toLowerCase();
                return "";
        }
}

I added the test i > 0 because it seems substring() kept throwing an indexoutofbounds exception for files with no extension.

Code:

---

class JavaFilter extends javax.swing.filechooser.FileFilter{
  String extension;
  public boolean accept(File file){
  if(file.isDirectory()) return false;
  String filename = file.getName();
  int i = filename.indexOf('.');
    if (i > 0){
    extension = filename.substring(i);
    }
    if(extension.equals(".java")){
    return true;
    }
    return false;
  }
  public String getDescription() {
  return ".java files";
  }
 }

And that worked?

Yeah it works pretty good now. The exception was only being thrown when i browsed on over to my C:\ drive. For some reason i have .java files on C:\ that have no extension.
