Transcribed Image Text:It is required to develop an application in Java to perform some operations to store
information about items in a store. The application will have the following classes:
(A) An abstract class called item having foliowing data fieids (private):
itemName (String), itemNumlingi, makeStringl, pricejdouble) and following
methods:
() Default constructor - without any parameters,
(i) Constructor having 4 parameters to initialize ali data fields,
(i) Set and get methods for all data fields separately.
(iM) tostring method to retum string representation of all data members,
(M Abstract method totalPrice to return total price.
(8) Write a concrete class (with implementation of all methods) called Storeltem,
which inherits the properties of class item. This new class has the following
additional members
Data fields (privatel quantity (int), disceuntRateldouble). Note that discountRate is
% of the sale price.
Methods. (public):
Default constructor- without any parameters
(i Constructor with 6 parameters.
(i set and get methads for both data fields separately.
(ivl totalPrice returns price multiplied by (10 - discountRate/100) further
multiplied by quantity.
(v testring retums String equivalent of all attributes (including that of Item).
(vi Print outputs all attributes (including that of Item) and also outputs the total
price.
(C) Write a class called Store having anly main method to test all functionalities of
class Storeltem
