使用JFileChooser获取目录中的所有文件名？

Question

I'm using this bit of code:

 fileBrowser() {
      String toReturn = null;
      JFileChooser Chooser = new JFileChooser();
      int choosen = Chooser.showOpenDialog(fileBrowser.this);
      if (choosen == JFileChooser.APPROVE_OPTION) {         
            System.out.println(Chooser.getCurrentDirectory().toString()+"\\"+Chooser.getSelectedFile().getName());
      }

  }

To get the selected file name and location, which is all working fine. I was wondering as an addition, is there also a way to get all the filenames in that directory as well? something like .getAllFiles() I've had a search around and can't find one?

Thanks in Advance.

Answer 1

Sure, use

File[] filesInDirectory = chooser.getCurrentDirectory().listFiles();

Then you can iterate over that array:

for ( File file : filesInDirectory ) {
    System.out.println(file.getName());
}

Answer 2

Well, there's File.list() . This will list all files by their name from the specified directory (ie File ). But this will also return directory names. In order to circumvent that, use the other File.list(FilenameFilter filter) method that will enable you to filter out directories from the listing.
