Answer 1

List lines = Files.readAllLines(Paths.get("res/file.txt"));
//перебираете циклом
for(String s : lines)
{
s = "Бла-бла-бла!"
}
/* Если нужно удалить - для перебора используйте Iterator.
Не забудьте : */ 
Files.write(Paths.get("res/file.txt"), lines);
//иначе результат не запишется

With FileWriter and BufferedWriter also.
