Question

I have written a method for closing files

private void closeFiles(Closeable ... files) {
    for (Closeable file : files) {
        if (file != null) {
            try {
                file.close();
            } catch (IOException ioe) {
                // org.apache.log4j.Logger
                logger.error("Unable to close file.", ioe);
            }
        }
    }
}

and then I found out that Guava provides the closeQuietly method which basicaly does the same thing. The only difference is using java.util.logging.Logger for logging. If an exception occurs in Guava, will it be logged into a file (configured for log4j) or not?

Answer 1

I think not. You has to write own handler. See for example
Routing java.util.logging messages to Log4J
