How to write data to file.txt with BufferedWriter or FileWriter?

Question

Java

I am writing text data to a file by code

public void writer (String file, ArrayList array) throws IOException{
BufferedWriter writter = new BufferedWriter(new FileWriter(file));
for (String s: array){
writter.write(s + "\n");
}
writer.close();
}

it works fine, BUT if the text is like this -> "Secrétaire général / Generalsekretär"
then it writes it like this -> "Secr?taire g?n?ral / Generalsekret?r"
I work in Netbeans, and if I start the project in it, it writes normally, but if I run the already assembled file from windows, it writes with such characters, I read that the text encoding might not be the same, but I didn’t understand how to fix it. Or is it not the coding? maybe there are some examples?

Answer 1

OutputStreamWriter writer =
             new OutputStreamWriter(new FileOutputStream(file), StandardCharsets.UTF_8)); // тут можно указать кодировку
