Hi.

 I have a couple of related problems thats why am putting at one place

1: I want to make a file chooser that just choose the last folder in the tree structure
of the directories in which there are  files . ant not to allow the user to select the
files. that is just folder (directory) and not the files



2:

and now i have got the users folder path in which his/her java files are residing,  i want to know

>>> how to read all the files term by tem and do manipulation of any kind on each file.

what i have thought is to read the name and path of every file and put that all in
a vector but how to do it i dont know



kindly help me am in real trouble..................

 
     waiting for realy a kind reply.

1. In the JFileChooser class you can specify the mode (only directories, only files, both) and filters.
2. Once you have a Directory selected, the file choodser will return to you an java.io.File object. In this File object, if is a directory you can call the method listFiles(), which will return to you an array of File objects. The rest depends on you (what you will do with the files).

Nandini,

1. Extend JFileChooser and call setFileFilter().  All you have to do is extend the javax.swing.filechooser.FileFilter abstract class to implement to just show File objects where isDirectory() returns true and listFiles does not return a 0 length array.

Then override aproveSelection so that folders you can accept have contents of the right type.

2. Call listFiles on the File returned and iterate through the File array that is returned, call getPath() which returns a string with the full path of the file.  Do an addElement to the Vector and thats that!

Regards,

Chrisos.
