Logger slf4j advantages of formatting with {} instead of string concatenation

Question

Is there any advantage of using {} instead of string concatenation?

An example from slf4j

logger.debug(\"Temperature set to {}. Old temp         


        

Answer 1

Another alternative is String.format(). We are using it in jcabi-log (static utility wrapper around slf4j).

Logger.debug(this, "some variable = %s", value);

It's much more maintainable and extendable. Besides, it's easy to translate.
