Write the printitem () method for the base class. sample output for below program: last name: smith first and last name: bill jones

The question involves basic polymorphism. The following is the partial flow of the program.

baseItemPtr = new BaseItem ();

baseItemPtr. setLastName ("Smith");

derivedItemPtr = new DerivedItem ();

derivedItemPtr. setLastName ("Jones");

derivedItemPtr. setFirstName ("Bill");

itemList. add (baseItemPtr);

itemList. add (derivedItemPtr);

for (i = 0; i < itemList. size (); + + i) {

itemList. get (i). printItem ();

}

return;
