Most common use case of logger declaration looks like

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

...

private static final Logger logger = LoggerFactory.getLogger(CurrentType.class);

It's almost fine, but it could be more compact:

import org.slf4j.Logger;

 ...

private static final Logger logger = Logger.getLogger(CurrentType.class);

Before java 8 it was not possible (Logger is an interface, not abstract class), now since the minimum required version is 9, the static initialization method can be introduced in the interface.
