  • 0

I’d like to receive a clarification on the following:

Every class that has something to say in my program , creates its own logger like this

public final static Logger logger = Logger.getLogger(ClassName.class);

I was thinking ….

Why is it public? Why is it customary to make it public?

– Logger is never reused from outside the class it was created

Can there be a generic logger used throughout the program instead of having each class maintain its own?
– Seems like ClassName is used as part of logging only to indicate WHAT class said what. Perhaps it is possible to pass a reference to the class name to the logger instead.

Please help me clarify

    The only reason to make it public is if you want it to be reused outside of the class.

    You can have a single logger instance per you application, but you lose granularity of the messages available for configuring package or class level logging facilities.
