/*
  2. Sa se defineasca o clasa StrTok, cu acelasi rol ca si clasa
StringTokenizer, dar cu mai putine functii.
Constructori:
    StrTok (String text, String delim);  // delim=sir delimitatori
Metode publice:
    boolean hasMoreTokens();  // daca mai sunt cuvinte
    String nextToken();       //  urmatorul cuvant

Sa se verifice metodele clasei prin extragerea cuvintelor dintr-un text
(cum ar fi acest text), separate prin spatii, punct, virgula, punct-virgula.
