لدي مشكله مع جملة inline if

char activity = s.next ().charAt ( 0 );

                String t = ( activity == 'A' | activity == 'S' ) ? "Valid" : "Invalid";

                System.out.println ( t );

اقتباس

 

char activity = s.next ().charAt ( 0 );

String t = ( activity == 'A' | activity == 'S' ) ? "Valid" : "Invalid";

System.out.println ( t );
