Почему PrintWriter иногда создает файл, но он не создает файл в другое время?

Question

Иногда PrintWriter делает файл для меня автоматически. Есть ли способ, которым он может работать все время? Я не знаю, почему он не работает каждый раз. Вот мой код.

String fileName = date + "-" + title; 

    //Write to file 
    try(PrintWriter writer = new PrintWriter(fileName, "UTF-8")) 
    { 
     writer.println(articleURL); 
     writer.println(body + "\n"); 
     for(String link: links) 
     { 
      writer.println(link + ","); 
     } 
     writer.close(); 
    } 
    catch(Exception e) 
    { 
     e.printStackTrace(); 
    } 

Это ошибка я получаю при попытке загрузить конкретный файл

Answer 1

имя файла, имя каталога, или синтаксис метки тома неверен

Это означает, что вы не может иметь ' или ? в имени файла.

Примечание. Я попытался найти дубликат в почти 2000 обращений к этой ошибке в stackoverflow, но не смог найти точное совпадение.
