What is the most efficient/elegant way to dump a StringBuilder to a text file?
You can do:
outputStream.write(stringBuilder.toString().getBytes());
But is this efficient for a very long file?
Is there a better way?

Answer
As pointed out by others, use a Writer, and use a BufferedWriter, but then don’t call writer.write(stringBuilder.toString());
instead just writer.append(stringBuilder);

it doesn’t accept a
java.nio.Charset
. BAD. You should always specify a Charset explicitly.it’s still making you suffer a
stringBuilder.toString()
. If the simplicity is really what you’re after, try the following from the Guava project:
