File chooser question

Hi,

I am trying to build a gui using java that allows the user to go thru
filechooser and pick any file(s) and/or directories. If a file or files
are chosen then the names of the files are appended to a list. If a
directory is chosen then the names of all the files in the directory
should be appended to the list.

I already have most of this code written up. However the code I have
does not distinguish between a file and a directory so it doesn't know
to open the directory. I was hoping there might be some built in
function that would determine this for me but I can't seem to find it.

I am still very new to Java and am trying to teach myself. Any help
would be appreciated.

You will want to check out the File API. Look for isDirectory ().

int returnVal = chooser.showOpenDialog(parent);
if(returnVal == JFileChooser.APPROVE_OPTION) {
File[] files = chooser.getSelectedFiles() ;
for(int i = 0 ; i < files.length ; i++){
File f = files[i] ;
if(f.isDirectory()){
String[] filenames = f.list() ;
//append to your list
}
else{
//append f to your list
}
}
}
