import java.io.File;

public class Main {
   public static void main(String[] args) {
      File file = new File("/data");
      if (file.isDirectory()) {
         String[] files = file.list();
         if (files.length > 0) {
            System.out.println("The " + file.getPath() + " is not empty!");
         }
      }
