Why do we declare Loggers static final?

Question

In Java, why is it best practice to declare a logger static final?

private static final Logger S_LOGGER

Answer 1

Ideally Logger should be as follows upto Java 7, for giving no Sonar and giving a Compliant Code: private: never be accessible outside of its parent class. If another class needs to log something, it should instantiate its own logger. static: not be dependent on an instance of a class (an object). When logging something, contextual information can of course be provided in the messages but the logger should be created at class level to prevent creating a logger along with each object and hence preventing High Memory footprint. final: be created once and only once per class.
