If you do not, you definitely get fail Assignment Brief and Guidance: Scenario : (continued from Assignment 1) Your team has shown the efficient of UML diagrams in OOAD and introduction of some Design Patterns in usages. The next tasks are giving a demonstration of using OOAD and DP in a small problem, as well as advanced discussion of range of design patterns. Tasks: Your team is now separated and perform similar tasks in parallel. You will choose one of the real scenarios that your team introduced about DP in previous phase, then implement that scenario based
on the corresponding class diagram your team created. You may need to amend the diagram if it is needed for your implementation. In additional, you should discuss a range of DPs related / similar to your DP, evaluate them against your scenario and justify your choice. In the end, you need to write a report with the following content: A final version of the class diagram based on chosen scenario which has potential of using DP. Result of a small program implemented based on the class diagram, explain how you translate from design diagram to code. Discussion of a range of DPs related / similar to your DP, evaluate them against your scenario and justify your choice (why your DP is the most appropriate in that case). Learning Outcomes and Assessment Criteria Pass Merit Distinction LO 3 Implement code applying design patterns P3 Build an application derived from UML class diagrams. M3 Develop code that implements a design pattern for a given purpose. D3 Evaluate the use of design patterns for the given purpose specified in M3. LO4 Investigate scenarios with respect to design patterns P4 Discuss a range of design patterns with relevant examples of creational, structural and behavioral pattern types. M4 Reconcile the most appropriate design pattern from a range with a series of given scenarios. D4 Critically evaluate a range of design patterns against the range of given scenarios with justification of your choices.

2 | P a g e This class diagram is about a movie management system. The system will display all movie available for user to search and watch when they launch the app. The administrator will management all the movie in the system, he can add, view, update, and delete movies. This is a simpler way to manage movies before developing into a larger project. Class MovieWebsite Show the list of movies Class Admin This class will manage all movies and execute functions (Add, View, Update, Delete) Class Movie This class is used to declare a property variable that will hold details about the movie. ID, Name, Director, and Category of the Movie. Create functions to retrieve and set values, then make them available to other classes for use. Class User This class can check information of movie by searching and watch movie they search.
2. Implementation 2.1.Code In order to make sure the application works effectively, we must employ code to manage. To create the management menu of movie, we have to go to the first steps that we need to create the movie class. Class Movie I shall first build the movie class. Here, I'll use the singleton pattern to make it simpler to declare variables for movie functions like add, view, update, delete, and watch movie as well as variables for id, name,
3 | P a g e director, and category. All of these characteristics have a significant role in both printing the output and afterwards influencing its functionality. Here I set the movie class as the main instance so that I may declare the variables and functions below. To optimize the selection, I'll use the "if - else" command as well as show input and authenticity to make the menu more realistic. The future management of both Admin and User will make use of each paragraph here. Figure 2 : Class Movie use singleton with add and view function In first paragraph is the add new movie function. In order for this add item to display the form that needs to be filled out, I have incorporated the code from the form in the movie class here.
5 | P a g e Here I also added a note in the menu to remind users to enter movie id to delete, and before deleting, you need to add the information of movie first. For the purpose of revalidating this delete statement for the id that was discovered or not discovered, I additionally utilized an additional if else statement. Then the next function is update movie: Figure 4 : The update movie function
6 | P a g e Here I also added a note in the menu to remind users to enter movie id to update, and before updating, you need to add the information of movie first. For the purpose of revalidating this update statement for the id that was discovered or not discovered, I additionally utilized an additional if else statement. Next is the search movie function: Figure 5 : The search movie function
8 | P a g e I have added a note to request user to enter the name to find the movie that users want to watch. Like other situations, you have to add all the information of the movie before you want to search and watch them. For the purpose of revalidating this watch statement for the name of movie that was discovered or not discovered, I additionally utilized an additional if else statement. Next we will come to the next step is setting variables as well as the calculations in the movie class. Here I will declare movie variables about id, name, director and category. All these properties are very important in printing the result. Figure 7 : Declare variables step After declaring the attributes in the movie class, next I will proceed to create forms according to each attribute. Each form will be filled with notes and we can optionally tweak any color to make this form easier to see.
9 | P a g e Figure 8 :Movie form to write information Admin will enter the information of all movie into this form such as ID, name, director, category. there are also some notes for admin like suggestion to fill in ID of movie. Below this form, we also have information verification item, it means that when admin fill in incorrectly, an error message will be displayed and the admin have to re-enter them. If admin enter correctly, the system will also notice that admin has filled in the information successfully.
11 | P a g e Figure 11 : Validation information (2) As you can see, these message line will appear when you skip the step of filling in the information. Finally, all steps of filling in the information will end up with ShowInformation function will show the result. Figure 12 : Final function will show the result on the screen
12 | P a g e Then we move to Program file where I create all interface for this program. Class Program The menu interface code for Admin After completing the necessary function on the Class Movie, we come to code about interface. Firstly, we have the main menu when we launch the program which have three options one for admin, two for user, and three for exiting the program. Figure 13 : Main menu interface coding
