Check if File is Folder

[Mathew Mintalm]

Hello, im making my own JTree, that reads files from system

And i have strange issue, if folder is empty its icon is like normal file (displaying at JTree)

So I guess i will have to check if file.. is folder?

What have i tryed so far? Checking file extension, thought that if extension doesnt exist it may means that its folder, bur doesnt work:

String patch = selectedNode.getAbsolutePath();
int dotPos = patch.lastIndexOf(".");
String extension = patch.substring(dotPos);
System.out.println("File Extension: " + extension);

Any solutions?

Thanks in advance!

The isDirectory() method of the java.io.File class would seem to be a pretty good candidate...
