PLAGIARISM: When you submit an assessment task, you are declaring the following 1. It is your own work and you did not collaborate with or copy from others. 2. You have read and understand your responsibilities under the University of Wollongong's policy on plagiarism. 3. You have not plagiarised from published work (including the internet). Where you have used the work from others, you have referenced it in the text and provided a reference list at the end ot the assignment. Plagiarism will not be tolerated. Students are responsible for submitting original work for assessment, without plagiarising or cheating, abiding by the University’s policies on Plagiarism as set out in the University Handbook COURSEWORK SPECIFICATION OBJECTIVES This assignment aims to provide you with some experience in writing codes using Java programming language that covers the following topics:  Classes and Objects  Interaction between Classes Remember that: 1. All programs should be able to run on the lab’s computers. 2. You must put the following information on the header of each text and source file you will be submitting in this assignment: Student’s full name: Student’s ID: Modification Date: Purpose of this file (or program): 3. Assignments that are not able to be compiled will result in zero mark given to the assignment. 4. You must only use the Java features that have already been covered in the lectures TASKS: This assignment will require you to design a set of classes that work together to simulate the items stored in a warehouse. You are then required to write a Java application to demonstrate how the objects from these classes interact. In this assignment we will assume that a warehouse, which is owned by a company, is an object and it can keep many containers (for shipping purposes for example). A container is also an object that can keep many items of different type which may belong to a particular company. To demonstrate this, your application should declare and implement the classes described below. The Warehouse Class This class is used to represent a warehouse. The class should contain attributes for the following information:  The warehouse name  The warehouse location  The owner (an object reference variable of type Company)  A list of containers stored in the warehouse (use an ArrayList to represent this where Container is a class described below) under University Policy Directory and in Faculty handbooks and subject guides. under University Policy Directory and in Faculty handbooks and subject guides. The class should have a default constructor and also a constructor to initialize the attributes with the values passed as parameters. Include methods to set each attributes individually, a toString() method to return a String containing the warehouse’s details, and a method to calculate and return the total value of a warehouse (the sum of the total value of each containers in the warehouse). The Company Class This class is used to represent a company. The class should contain attributes to represent the following information:  The company name  The company’s address  The contact number Include a default constructor and a non-default constructor to initialize the attributes with values passed through parameters. Include also the toString method to return the details of the company. The Container Class This class is used to a container carrying goods to be stored in a warehouse. The class should keep the details of:  The container id  The size of the container (e.g. 8ft, 10ft, 20ft, or 40ft containers)  A list of items stored in the container (use an ArrayList to represent this where Item is a class described below) The class should have a default constructor, the set method to change the id and the size separately, the get methods to return individual attribute’s value, a method to add a new item to the ArrayList, a toString() method to return the details of the container, and a method to calculate and return the total value of a container (the sum of the total price of all items stored in the container). The Item Class The Item class is used to represent an item stored in a container. The Item class should include the following information.  The item’s id  The item’s description  The price per unit  The quantity in hand  The supplier supplying the item (an object reference variable of type Company described above) The class should implement a default constructor, set methods for individual attributes, and get methods for each attributes. Include also a toString() method to return a String to display the item’s details and a method to calculate and return the total price of an item. The main application Write another class to be the main application that simulate the interaction between all the classes above. Your application should keep an ArrayList of Warehouse that allows many Warehouse objects to be stored. The following operations should be available:  Create a new Warehouse object  Add a Container to an existing Warehouse. This option will involve adding items to the container before the container is added to the Warehouse.  Show the total value of: o A warehouse o A container in a warehouse o An item in a container  Display the following information o All Warehouse information o All Containers in a Warehouse o All Items in a Container Remember to include meaningful comments and use meaningful variables and methods names. A loop should be used to allow the user to continuously perform various operations until the user chooses to quit from the application. Include also necessary validations.
