Questo codice non funziona:

  public static void main(String []args){

          System.out.println( g );
         char g = 'A' ;


      }


Questo sì:


  public static void main(String []args){


         char g = 'A' ;
         System.out.println( g );

      }

In altri linguaggi si può fare tranquillamente( esempio VBA di Excel ).

Grazie
