In java Problem: An online grocery store sells items on a web page. A user adds items to a basket and he clicks on the submit button when he completes. The store sells food and electronic items. The electronic items require VAT payment of 15 percentage of their prices. There are packed and lose food. The lose food is measured in weights. User specifies the weight amount or the quantity in his selection of items depending on its type. The price is computed as the product of the price per item or the price per weight and the weight or quantity are given by the user. Write an application that reads a user basket list and produces the bill receipt. Check the given samples of input/output in the figures below. The bill receipt contains the list of item details in decreasing order according to the price computed for each item. Use the selection sort1 to sort the items in the list and do not use java given sort method. Selection sort is an algorithm used to arrange elements in a list. It selects the smallest element from an unsorted list in each iteration and places that element at the beginning of the unsorted list. Provide required classes for items with constructors, accessor, and mutator methods. Your tester class Hw3_yourID includes methods to: ● Get correct input file name ● Read the list of items ● Sort the list of items in decreasing order using selection sort method ● Display the data and compute the total amount due In java
