How to get an array of current directory listing including file/directory name, last modified, and size in Java?

I know the code below will return the current files or directories in a directory:

import java.io.File;

public class test {

  File f = null;
  String[] paths;


     // create new file
     f = new File(".");

     // array of files and directory
     paths = f.list();

     // for each name in the path array
     for(String path:paths)
     {
        // prints filename and directory name
        System.out.println(path);
     }
}

but I need to return the results like below with file size, last date modified, and filename. I am not seeing how to do this with the File class methods. Any help?

For example...

File f = new File(".");

File[] files = f.listFiles();

DateFormat df = new SimpleDateFormat("MMM dd HH:mm:ss");

// for each name in the path array
for (File file : files) {

    System.out.printf("%4d %s %s%n", file.length(), df.format(file.lastModified()), file.getName());

}

Which outputs something like...

  85 Oct 21 16:04:17 manifest.mf
