 Then, it adds a codice_3 to the codice_1.Finally, it attempts to retrieve the added codice_3 and cast it to an codice_6—an error in logic, as it is not generally possible to cast an arbitrary string to an integer.List v = new ArrayList();
v.add("test"); // A String that cannot be cast to an Integer
Integer i = (Integer)v.get(0); // Run time error
Although the code is compiled without error, it throws a runtime exception (codice_7) when executing the third line of code.
