Excellent Research Article

I read this morning an excellent research article on using Web 2.0 technologies in higher education: "Students' Acceptance of Web 2.0 Technologies in Higher Education: Findings from a Survey in a Romanian University", Proceedings DEXA 2010 Workshops, IEEE Computer Society Press (Elvira Popescu, SPeL2010), which I recommend for its content, as well as for its valuable bibliography.

As further reading, I am especially tempted by number 7 in this bibliography: M. Homola and Z. Kubincova, "Taking Advantage of Web 2.0 in Organized Education (A Survey)", Proc. ICL 2009, pp. 741-752.

I was not aware of the wealth of literature and preoccupation regarding the use of  Web 2.0 for learning and for research. Thank you, Elvira, for introducing me in this world!

Colecţii şi clase generice

Pachetul java.util conţine biblioteca API Collection (Collection Framework), în care sunt definite clase corespunzătoare unor structuri de date precum  Set, List, ArrayList, LinkedList, Vector, Map, Hashtable, Stack, etc. Aceste clase definesc metode de nivel înalt pentru căutarea şi sortarea elementelor lor. Obiectele claselor din cadrul de lucru pentru colecţii utilizează o referinţă Object pentru a indica spre elementele lor, astfel încât în cadrul aceleiaşi liste, de exemplu, se pot stoca tipuri diferite de obiecte, ca în programul Colectii redat mai jos.
