Problem Description As a soccer player I always have a hard time selling my used soccer requitements and I realized that most of my teammate have used soccer requitements as well that they want to sell but don't know where to go and sell those things and end up wasting them and some even throw them in the trash which is not good for the environment. I am Developing an online shopping application that will allow soccer players sell their existing product if they want to. The type of product will be soccer ball, jerseys, shorts, shin guard, socks and cleats, the reason why I choose this is because have a lot of soccer item that I have used in the past, but I don't know where to sell them Prepare a design for a Java program that would solve a significant business problem. Four business case examples are provided with the assignment (See Page 3), but you are strongly encouraged to use your own real-world business case. If you use one of the provided examples, you will need to create your own problem description and enhance the case. It is not acceptable to copy and paste the description given in the assignment. To limit the problem to a reasonable scope, assume the system will be used in a small business environment. Note also that this assignment does not require you to write/submit a java program Research and evaluate the essential requirements and usage of such a system, and create a design for a Java program that would solve the problem. Your design report should be at least three pages and at most four pages. For full points, your solution must include all five of these sections. Please clearly identify the sections in your document: (1) Problem Description: Describe the salient features and main components of the business problem. Document the sources you used to obtain the problem examples or business case information. (2) Interpretation: Does the business problem make sense? Did you notice any unmentioned requirements that should be addressed by a solution? If you have experience relating to the business problem, can you identify anything that should be resolved differently than stated in the business case? (3) Classes: Detail the specific classes that would be required for the problem solution. Use the concepts from Chapter 8's first two sections to determine what classes are best suited to the problem - as noted in Chapter 8, classes typically are related to specific "nouns" in the problem description (4) Class Methods: For each of the classes from section (2), describe in detail (but do not implement) the methods that would be required in each class. Explain the purpose and the action for each method. Remember that methods are typically "verbs" or "actions" related to the problem and its solution. (5) Summary: Explain why your classes and methods completely solve the business problem outlined in Section 1 and discuss whether your assumptions and alternatives are suitable, appropriate, and completely solve the
