Write the printItem() method for the base class. Sample output for below program:

Last name: Smith First and last name: Bill Jones 

// ===== Code from file BaseItem.java ===== public class BaseItem { protected String lastName;

public void setLastName(String providedName) { lastName = providedName; return; }

// FIXME: Define printItem() method

/* Your solution goes here */

} // ===== end =====

// ===== Code from file DerivedItem.java ===== public class DerivedItem extends BaseItem { private String firstName;

public void setFirstName(String providedName) { firstName = providedName; return; }

@Override public void printItem() { System.out.print("First and last name: "); System.out.println(firstName + " " + lastName); return; } } // ===== end =====

// ===== Code from file ItemInventory.java ===== import java.util.ArrayList;

public class ItemInventory { public static void main (String [] args) { BaseItem baseItemPtr; DerivedItem derivedItemPtr; ArrayList itemList = new ArrayList(); int i = 0;

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; } } // ===== end =====
