A Java application developed to solve a small business problem related to student management. The application features a graphical user interface (GUI) with functionalities for reading and writing data from/to text files, working with a collection of student data (searching, finding min/max, sum, etc.), and handling errors to prevent the application from crashing. The design, implementation, and testing of the application, including the program structure, class explanations, important algorithms, and error handling. It also includes a test plan, test log, and screenshots of the application's features such as adding, editing, deleting, and sorting students by name. The document demonstrates the student's learning outcomes, such as understanding basic programming skills, the OOP paradigm, file handling, and GUI development, as well as the application of the MVC model and JUnit testing.

The problem requires a graphical user interface with features that required reading / writing data from text file, working with a collection of data (searching for item / min / max / sum / etc.). The application must handle errors so that it will not crash at end user side. The application also need to be fully tested before the production phase. You need to write a technical report about the development of the application. Content of the report should cover design, implementation and testing. In the end you need to demo your application, explain your code and answer technical questions.
Learning Outcomes and Assessment Criteria LO1 Understand basic programming skills and OOP paradigm LO2 Understand how to detect errors and handle errors LO3 Understand how to working with files in applications LO4 Understand how to build GUI application To get Pass (5 – 6.5 points)
Currently, the use of word or excel to save information as well as manage students is more and more. This leads to manual student management that is difficult, delayed, and impossible to control the right amount. Therefore, I decided to create an application that supports student management in java. This app helps me to know the exact student information and also the number of students in that class. Here is my presentation of my application.
The java program that I created has helped me with the following: I can enter data and can edit and delete them easily and understandably. Displays include the following values: +ID +NAME +PHONE +AGE +GENDER +EAMAIL And function keys like: Add new, edit, delete and sort by name. All information is displayed clearly for users to understand. Our program can reorder students with the function of sorting students by name. With an eye-catching interface that is easy to use, it is suitable for everyone from non-techies to tech-savvy people.
III. Wireframe UI design The basic interface of the program will include labels, corresponding to it are text fields and combo boxes for users to enter corresponding information. Besides, thereare buttons for users to interact with the entered data. Finally, a table to display theentered results. Implementation 1Explain program structure
