Я написал правильно все на мой взгляд, но валидатор не принимает. Неужели в задании чтобы записывать в файл нужно использовать исключительно PrintWriter. Я так не думаю. Не понимаю где я ошибся. Подскажите.
public void save(OutputStream outputStream) throws Exception {
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(outputStream));
writer.write(staticString);
writer.write(this.i);
writer.write(this.j);
writer.close();
}
public void load(InputStream inputStream) throws Exception {
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
staticString = reader.readLine();
this.i = Integer.parseInt(reader.readLine());
this.j = Integer.parseInt(reader.readLine());
reader.close();
