Question: Consider the following code in C++: Here *Lp will be a deep copy of L, containing a copy of each foo object. Try to write

Consider the following code in C++:

$template class cloneable_list : public list { public: cloneable_list* clone () { auto rtn = new cloneable_list(); for (auto e : *this) { rtn->push_back (e); return rtn; }; cloneable_list L; cloneable_list* Lp = L.clone (); %3D$

Here *Lp will be a “deep copy” of L, containing a copy of each foo object. Try to write equivalent code in Java. What goes wrong? How might you get around the problem?

$template class cloneable_list : public list { public: cloneable_list * clone ()$

template class cloneable_list : public list { public: cloneable_list * clone () { auto rtn = new cloneable_list (); for (auto e : *this) { rtn->push_back (e); return rtn; }; cloneable_list L; cloneable_list * Lp = L.clone (); %3D
