Also it is far better to use a logging framework than writing directly to
System.out as you have more control over when and where the logs are written.
You can use java.util.logging (juli) directly or even a facade like SLF4j and
then use whatever implementation you like behind it. The advantage of the
facade is that the implementation (logback, log4j, juli) can be changed with
configuration and a new jar instead of code changes everywhere you write to the
logs.
With either method you can write logs at different levels (trace, debug, info,
warn error - juli does use different names though, same idea) and turn them
on/off in configuration and even dynamically.
