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 sort' to sort the items in the list and do not use
java given sort method.
