JFileChooser .txt extension

Question

I have developed simple notepad application in java . When I want to save file I want to add .txt extension to that file. This is working fine in file dialog

String filename;
FileDialog fd = new FileDialog(Editor.this,"Save File",FileDialog.SAVE);
fd.show();
if (fd.getFile()!=null)
{
    filename = fd.getDirectory() + fd.getFile()+".txt";
    setTitle(filename);
}

It's working fine in the FileDialog with finename.txt

But when I take

String filename;
JFileChooser save = new JFilechooser();

Try to add extension

filename =save.getDirectory() + save.getFile()+".txt";

It's not working how can i solve this issue?

If you do not give any sample input, the output you expect and what you get instead, nobody will be able to help — fge, Jun 15 '13 at 09:42
Is it me or does JFileChooser not even have getDirectory() and getFile() methods? — Davey Chu, Jun 15 '13 at 09:58

@daveychu `JFileChooser` has [`getCurrentDirectory()`](http://docs.oracle.com/javase/7/docs/api/javax/swing/JFileChooser.html#getCurrentDirectory%28%29) & [`getSelectedFile()`](http://docs.oracle.com/javase/7/docs/api/javax/swing/JFileChooser.html#getSelectedFile%28%29). — Andrew Thompson, Jun 15 '13 at 10:56
@AndrewThompson I was just wondering why topic starter posted non-compiling code. — Davey Chu, Jun 15 '13 at 14:34
@daveychu The question does flip between the AWT & Swing versions of a file chooser. Have to agree it is a little confusing though. — Andrew Thompson, Jun 15 '13 at 15:41

In JFileChooser to get the file you use:

File currentFile= save.getCurrentFile();

and only then you get what you need (for example the path):

String fileName = file.getPath();

On the side note, JFileChooser has a nice documentation, make sure you read it: http://docs.oracle.com/javase/6/docs/api/javax/swing/JFileChooser.html
