This program must be done in JAVA.

Write a program to monitor the flow of an item into an out of awarehouse. The warehouse has numerous deliveries and shipments forthis item (a widget) during the time period covered. A shipment out(an order) is billed at a profit of 50% over the cost of thewidget. Unfortunately each incoming shipment may have a differentcost associated with it. The accountants of the firm haveinstituted a last-in, first out system for filling orders. Thismeans that the newest widget are the first ones sent out to satisfyan order. This method of inventory can be represented by a stack.The Push procedure will insert an incoming shipment while a Popshould be called for a shipment out. Each data record in the textfile warehouse.txt will consist of one shipment per line withfields (separated by white space of) I or O (char) shipment comingIN or shipment going OUT # (integer) quantity of the shipment Cost(float) cost per widget of the shipment (Incoming only) Vendor(String) name of the company sending or receiving the shipmentWrite the necessary procedures to store the shipments received andto process the orders. The output for an order consists of thequantity and the total costs of the widget in the order. Eachwidget price is 50% higher than its cost. The widgets used to fillan order may come from multiple shipments with different costs. Ifthere are not sufficient widgets in inventory, use all theremaining and bill accordingly. When the simulation terminatesdisplay the total amount owed to each of the suppliers (incoming),the number of widgets on hand and the total profit.
