JAVA CODE Write a java set of classes that could be used to do simple calculations on geometricobjects. The set should include the following classes: a) Shapes ,containing abstract methods( a methods that is declared without animplementation) area and perimeter b) Rectangle, a subclass of Shape, containing a constructor (with parameters forlength and width) along with methods area and perimeter. c) Triangle, a subclass of Shape, containing a constructor (with parameters for the three sides of a triangle) along with methods area ( s = (a+b+c)/2, A = sqrt( s(s-a)(s-b)(s-c) ) ) and perimeter d) Square, a subclass of Rectangle, containing a constructor (with a parameter for thelength of a side) and methods that invoke the methods of the Rectangle class todetermine the perimeter and area of a square.

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 following data fields (private): itemName (String), itemNum (int), make(String), price(double) and following methods: (i) Default constructor - without any parameters, (ii) Constructor having 4 parameters to initialize all data fields, (iii) Set and get methods for all data fields separately, (iv) toString method to return string representation of all data members, (v) Abstract method totalPrice to return total price. (B) 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 (private): quantity (int), discountRate(double). Note that discountRate is % of the sale price. Methods (public): (i) Default constructor - without any parameters Constructor…
