I have a Java library, quite a huge one.

I'm asking regarding Best Practices of structuring the source.

For example, the logging sybsystem:

Option 1: All in one package, named to sort nicely

Log - static accessor
LogMonitor - interface for log minotor
LogMonitorBase - abstract class
LogMonitorStdout - print log to console
LogWriter - interface for file logger
LogWriterSimple - log writer with just one log file
LogWriterArchiving - log writer that handles old log files

Option 2: Subpackages for Monitors and Writers, with better names

Log
monitors/LogMonitor
monitors/BaseMonitor
monitors/StdoutMonitor
writers/LogWriter
writers/SimpleLog
writers/ArchivingLog

The second maybe looks better, but perhaps it's not so practical from the java point of view (two extra packages).

What do you suggest as the best practice here? A lot in one package, grouped by naming prefixes, or a lot of subpackages with better names?
