       public static void main(String[] args) {

             String path = "project//doc//index.html";

             String result = displayDetails(path, 2);

             System.out.print(result);

D.
An InvalidPthException is thrown at runtime.

E.

Risposta B.

Si crea un File con ingresso "project//doc//index.html". Poi dal File si estrae il path. Infine si stampa il 3° elemento del percorso :

p.getName(0).toString()) à project

p.getName(1).toString()) à doc

p.getName(2).toString()) à index.html
