Question

Here is my code that I have which is pretty simple and to the point:

public void sendMessage(String message)
{
    writer.println(message);
    writer.flush();
}

I don’t really like to use PrintWriter cause it tends to swallow IOExceptions, this is really the only thing I’m using it for besides sending byte arrays. What can I use instead that won’t consume IOExceptions and will still give me the functionality of PrintWriter?

Answer 1

I’d recommend using a plain Writer or a BufferedWriter

public void writeMessage(BufferedWriter bw, String message) throws IOException {
    bw.write(message);
    bw.newline();
    bw.flush();
}

or

public void writeMessage(Writer writer, String message) throws IOException {
    writer.write(message);
    writer.write(System.lineSeparator());
    writer.flush();
}

But obviously it depends on what functionality of PrintWriter you want to retain.
