Convert InputStream to byte array in Java

Question

How do I read an entire InputStream into a byte array?

Answer 1

Java 8 way (thanks to BufferedReader and Adam Bien)

private static byte[] readFully(InputStream input) throws IOException {
    try (BufferedReader buffer = new BufferedReader(new InputStreamReader(input))) {
        return buffer.lines().collect(Collectors.joining("\n")).getBytes();
    }
}

Note that this solution wipes carriage return ('\r') and can be inappropriate.
