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;

$\}$

$//$ 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;

$\}$

@Override

public void printItem$()\{$

System.out.print$("$First and last name: $")$;

System.out.println$($firstName $+""+$ lastName$)$;

$\}$

$\}$

$//=====$ 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;

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$()$;

$\}$

$\}$

$\}$

$//=====$ end $=====$
