question: private static String [ ] processObjectClasses ( final String objectClass ) { String [ ] objectClasses = null ; if ( objectClass != null ) { objectClasses = objectClass . split ( "," ) ; } if ( objectClasses != null ) { String objClass = null ; for ( int i = 0 ; i < objectClasses . length ; i ++ ) { objClass = objectClasses [ i ] ; if ( objClass != null ) { objectClasses [ i ] = objClass . trim ( ) ; } } } return objectClasses ; }
target:  Procesa un string con clases separadas por , para devolver un array
