import org.apache.commons.io.IOCase;
import org.apache.commons.io.comparator.NameFileComparator;
import org.apache.commons.io.filefilter.FileFileFilter;
public class IOTester {
   public static void main(String[] args) {
      try {
         usingNameFileComparator();
      } catch(IOException e) {
         System.out.println(e.getMessage());
      }
   }
   public static void usingNameFileComparator() throws IOException {
      //get the current directory
      File currentDirectory = new File(".");
      NameFileComparator comparator = new
      NameFileComparator(IOCase.INSENSITIVE);
      File[] sortedFiles = comparator.sort(currentDirectory.listFiles((FileFilter)FileFileFilter.FILE));
      System.out.println("Sorted By Name: ");
      for(File file:sortedFiles) {
         System.out.println(file.getName());
      }
   }
}
