there is a parser

try{
        	//конектимся
            Document doc = Jsoup.connect("http://" +parserParam).get();
            //добавляем в список из элементов все что лежит между тегами <html> </html>
            List<Element> elements = doc.select("html");
    		
            //выводим на клиента все что спарсилось	
            out.print(elements);  
        }
        //перехватываем исключение если че
        catch(Exception e){
        	e.printStackTrace();
        	out.print("ERROR, possible somthing wrong with your query");
        }
        //закрываем поток вывода
    out.close();

The question is, how can I write what I was able to write to a file? I have already tried both FileInputStream and FileWriter at the moment when I call the .write() method Eclipse underlines it with an error

In what format?
The simplest is to convert your List to json using any of the 100500 libraries (I like Gson for example), and write to the file as a string.
