How to get file name list?

 If your path is: /home/develhelper/mydir try:

  File f = new File("/home/develhelper/mydir");
  String [] list = f.list();

Thanks for your quick response. I'm going to test it. In the meantime, could you please tell me how to get the subfolder names?

There are two possibilities:

- class FileSystemView (javax.swing.filechooser.FileSystemView).
- class File (java.io.File), that has methods that returns the files when that class represents a directory (the path name is a directory).

I tested the suggestion provided by girionis, but it doesn't return the files under subfolders.

  They should be in the list with the files and subfolders returned.

It returns the subfolder names, but it doesn't return the file names under subfolder.

It returns the subfolder names, but it doesn't return the file names under subfolder.

Use the method listFiles() instead list() which returns File classes and the recursively list the Files that are directories(isDirectory method).

File f = new File("/home/develhelper/mydir");
File [] list = f.listFiles();

for (int i=0;i<list.length;i++)
  if (list[i].isDirectory())  { // is a subfolder
     File [] subfolders=list[i].listFiles();
     // show then... and check if any are a directory
  }

Thanks! Amgs,

It seems that your answer is very close. One more question: how the method to return both the folder name and the file list?

Good job!
But it would be great appreciated if you can tell how to know which files directly under the given dir and which files under subfolder name.

I think I need to create a java bean to store the subfolder name and all file names under that subfolder.

This program already does that, since on the first tab level are the files of the given directory and on the second tab level are the files in the sub folders.
If you want another kind of solution you should adapt this small example.

Sorry, I didn't recognize this program already does that. You actually did an excellent job!
