import java.io.IOException;
 
public class HiddenFile {
 
   public static void main(String[] args) throws IOException { 
 
      File file = new File("/tmp/.hidden.txt");
 
      if(file.isHidden()) {
         System.out.println("File is hidden");
      } else {
         System.out.println("File is not hidden");
      }
   }
