LoggerIsNotStaticFinal

LoggerIsNotStaticFinal

In most cases, the Logger reference can be declared as static and final.


                 
//VariableDeclarator
 [parent::FieldDeclaration]
 [../Type/ReferenceType
  /ClassOrInterfaceType[@Image='Logger']
   and
  (..[@Final='false'] or ..[@Static = 'false'] ) ]
                

Example(s):


 
public class Foo{
    Logger log = Logger.getLogger(Foo.class.getName());					// not recommended

    static final Logger log = Logger.getLogger(Foo.class.getName());	// preferred approach
}
