1. Exceptions Complicate Code
protected void closeStreams() { if (currentObjectStream == null) { return; } try { currentObjectStream.close(); catch (IOException e) { Log.printf("couldn't close ObjectOutputStream for '%s'", currentFileName); currentFileStream.close(); Log.printf("couldn't close FileOutputStream for '%s'", currentFileName = null; currentFileStream = null; currentObjectStream = null;
