(y/n)"); s = scan.next(); if (s == "n") break; } } } } Thus, the first thing to do is create an abstract superclass and three subclasses. The superclass musthave as many members (fields and methods) common to type X, Y, and Z products as possible. Eachsubclass must have its constructor and a method to calculate the total that overrides the superclass'smethod.The advantage of inheritance is the ability to create an array of superclass objects to be filled withobjects of different subclasses. Thus, your inventory is still in one array. Use the product's index in thearray to build the product's ID (I would recommend starting with 1). In the superclass, create a staticvariable that holds the number of products available in the inventory. It must grow as reading from thefile progresses.Override a default tostring () method for a superclass such that it shows product ID, name, regularprice, and type.At this moment, make sure that all modifications you have made keep your application alive andworking.The next step is to add three new classes to the project:Create a class to represent the user - hardware store customer. You must decide what membersthis class needs. Ask the user to input necessary information.You may notice that the date is a complicated piece of data. Create a class Date that converts astring of the form of "mm/dd/yyyy" into an object with three fields – month, day, and year. Theclass constructor may do this job, but do not forget to check the string for correctness. Once youhave this class ready, input the date as a string with the following converting into an object oftype Date. Remember, if you read a string from the keyboard after a number, you may need tohandle the new line symbol left in the input buffer.The result of your application is an order that must have the customer's information, the date,the product information, and the total amount to pay. Thus, the third class to add is the classOrder. This class aggregates other classes. When all the information is collected, the order isready to be created and printed out. Outputting the order is the primary behavior of an objectof type Order, and it is the final step of your application. Thus, class Order aggregates thecustomer's info, date, product info, and total. Please note that type X and type Y products needonly regular price and amount to calculate the total, while type Z products must also considerthe date. The input and output examples for types Y and Z areUser: Vladimir KupermanThe inventory:1 Light Bulb 60W 3.02 Light Bulb 100W 5.990.150.25Туре XТуре хТуре YТуре YТуре ZТуре z3 Steel Bolt M54 Steel Bolt M85 Hose 25 feet10.06 Hose 50 feet15.0Your choice: 3Number of units: 1000What is the purchasing date?

Your code had some mistakes due to which it was going into an infinite loop which resolved. Now this…
