Reading lines from an InputStream without buffering

Question

Does Java have a simple method to read a line from an InputStream without buffering? BufferedReader is not suitable for my needs because I need to transfer both text and bin

Answer 1

Eventually did it manually directly reading byte after byte from the InputStream without wrapping the InputStream. Everything I tried, like Scanner and InputStreamReader, reads ahead (buffers) the input :(

I guess I missed a some cases like \r.

public static String readLine(InputStream inputStream) throws IOException {
    ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
    int c;
    for (c = inputStream.read(); c != '\n' && c != -1 ; c = inputStream.read()) {
        byteArrayOutputStream.write(c);
    }
    if (c == -1 && byteArrayOutputStream.size() == 0) {
        return null;
    }
    String line = byteArrayOutputStream.toString("UTF-8");
    return line;
}
