CSIT213 E-Commerce System Assignment 1: Java OOP Implementation Without Collections for Manual Array Management

Objectives

• To apply Object Oriented Design.
• To apply Object Oriented Programming.
• To implement solution in Java and IDE.

Tasks

The following class diagram serves as a prototype for an application that models an ECommerce Management System. The system consists of four main classes:

• ECommerceManager: Responsible for managing the overall operation of the system, including the handling of customers, products, and orders.
• Customer: Represents individuals who register with the system before placing orders through the e-commerce platform.
• Product: Represents the various items available for purchase in the e-commerce store.
• Order: Tracks details about each order placed by customers, including the product ordered, quantity, and order date.

Your task is to implement the classes shown in the diagram. In addition, you are required to write a separate class containing the ‘main’ method to test the functionality of the system. You should also take error cases into consideration when implementing the methods.

To simplify implementation, assume a fixed capacity of 100 customers, 100 products, and 100 orders and the maximum quantity ordered per product item is 10. In addition, each placement of order will generate a unique order ID in placeOrder method in ECommerceManager.

Test Code and automated grading

The testing code StudentAssertionTest.java has been provided to assist you to test your code.

You need to enable assertion in Java to enable the testing.

Ensure that you have passed all the test cases before submission, else zero marks will be awarded if the StudentAssertionTest.java failed to run.

Another comprehensive code will be used to automate the grading of your assignment.

Do not use any packages for the Java code as the automated grading will fail and will result in zero marks.

Requirements

• Please include the following information at the beginning of the Java source file.
  • Module code
  • Assignment name
  • Your UOW student number.
  • Your full name.
  • Your tutorial group.
• You must adopt good programming practices which include (but not limited to) the followings:
  • Descriptive variable, parameter and method names.
  • Readable source code with proper indentation.
  • Descriptive block comments in the source code and the test results.
  • Modular programming.
  • Avoid global variables.
• You must include additional test cases to thoroughly test the classes and the methods implemented in your solution by adding in more test cases in StudentAssertionTest.java.
• You should organize the sequence of the test cases so that the test results are readable.
• Do not use any packages for the Java code.
• Failure to compile and execute the code will result in zero marks awarded.

Submission

• Submit one zip file containing the FIVE Java classes and the execution results in a text file (output.txt) to Moodle. The FIVE classes are: Customer.java, Order.java, Project.java, ECommerceManager.java and StudentAssertionTest.java.
• Only zip format is acceptable. Do not use other compression format such as. 7z, gzip and rar.
• For full time student:
  • File name must be in the form of: TXXF_NAME_UOWID.zip where XX is your tutorial group, NAME is your full name (without space or underscore) and UOWID is your 7-digit UOW ID number (not SIM student ID number).
  • For example, T02F_JeffreyTan_8080426.zip
• For part time student:
  • File name must be in the form of: TXXP_NAME_UOWID.zip where XX is your tutorial group, NAME is your full name (without space or underscore) and UOWID is your 7-digit UOW ID number (not SIM student ID number).
  • For example, T02P_JeffreyTan_8080426.zip
