Get File Information

Question

Hi!
I wonder if you know any way to get the extension of a file, and his creation date too. I know File class exists, but this one does not contain these methods.
Do you know any way to get it both?
Thank you very much,

here.. I'm feeling generous...
import java.io.File;
public class Test
   public static void main(String[] args)
       // returns "ext"
       System.out.println(getExtension(new File("test.ext")));
       // returns null
       System.out.println(getExtension(new File("noextension")));
   public static String getExtension(File file) {
       String name = file.getName();
       int lastDot = name.lastIndexOf('.');
       if (lastDot == -1) {
           // there is no extension
           return null;
       return name.substring(lastDot+1);
}And I don't think you can get the creation date, because as stated, not all file systems support that.
