List is an Interface (Super type of ArrayList, LinkedList). when you sat List l = new ArrayList(); you are creating a subclass object with super class reference, thus you can access the methods of only super class but in case of overridden methods the subclasses method would be invoked.. In your case: List l = new ArrayList() you will only be able to invoke methods and fields declared inside. List<String> lista = new ArrayList<>(); HashMap<String, Integer> h = new HashMap<String, Integer>(); int countNostenySzam = 0; int himUtodSzam = 0; List<String> himNevTomb = new ArrayList<>(); List<String> nostenyNevTomb = new ArrayList<>(); List<Integer> himUtodSzamTomb = new ArrayList<Integer>() ArrayList< Vasarlas > vasarlasok = new ArrayList<>(); try { RandomAccessFile raf = new RandomAccessFile(penztar.txt,r); String sor; ArrayList<String> lista = new ArrayList<>(); for( sor = raf.readLine(); sor != null; sor = raf.readLine() ) { if( !sor.equals(F) ) { lista.add(sor); } else { vasarlasok.add(new Vasarlas(lista)); lista = new ArrayList<>(); } } raf.close(); } catch( IOException e
