It's more normal to do this:
public class Foo {
   private static final Logger logger = Logger.getLogger(Foo.class);
}The advantage is that you don't create a Logger object for every instance of the class in question.
The disadvantage is that it's common to cut and paste the line in question and then forget to change the class reference passed to the getLogger method, leading to some very mildly misleading logger output (not a big deal).
