- Have four main functions:
Create: To save information of student.
Read: To display all or found students.
Update: To update information of student.
Delete: To delete information of student.
- And have more sub-functions, such as:
Sorting ascending, descending information of students by their ID
Find student by id and/or name
III. UI Design
- Wireframing is a way to design a website service at the structural level. A wireframe is a layout of a web page that
demonstrates what interface elements will exist on key pages. It is a critical part of the interaction design process. Because the
aim of a wireframe is to provide a visual understanding of a page early in a project to get stakeholder and project team
approval before the creative phase gets underway, I decided to place it in this report to support my work become easy, and also
customer can understand my application which I designed for them. This is a wireframe of student management software:
- These are the fields for user to type and choose students’ information, including:
Text fields with rectangle shape which is the place to type student information, such as ID, Name, Birthday, Email,
Phone number.
Two radio buttons for choosing student gender.
- This is the two radio buttons to choosing for sorting ascending and descending students’ information by their ID
- This is the table for display the information of students for all or found students. **IV. Implementation

2. Classes: There are 4 classes in my program, including: ‘StudentController’ class: contains CRUD functions, check information functions, read/write file functions, sorting student information functions. Those functions have the mission to handle the data and then pass it to the class ‘MainFrame’ which is the view.
‘MainFrame’ class: contain button, table,…, return student information, getting from ‘StudentController’ class, to table functions. This class also handle the button events. ‘App’ is the class main which help running the program.
3. Program structure:
This is structure of my program, including 4 class, ‘Student’ class, ‘StudentController’ class, ‘MainFrame’ class. Whenever the program starts, the view appears and the ‘ReadDataFromFile’ function is called with its function passing the data from file to list and the data will be passed into the ‘ArrayList’, then the data from the ‘Database’ file are passed into the ‘ReadFile’ function. The view contain: Text field of id, name , birthday, email, phone number, and search id and name: to get text for handling. Radio button of choosing genders, add/delete/update functions, and sorting function. Button: Save, Delete, Update, Search Table to display the information of students Whenever user add interact with view, the view will receive user actions such as adding, deleting, updating, the view has the mission to receive data through text field such as id, name text field, the data will be passed into view, followed by controller, and given to a certain function to
handle, then the handled data will be passed into the ‘ArrayList’ and continuedly transferred to ‘WriteToFile’ function in order to write or override them into the ‘Database’ file. The ‘Database’ file, then, will be read by ‘ReadFile’ function, and after that data corresponding with user need will be returned to the view.
4. Important algorithms:
A. Adding student:
This is a flowchart of adding new student to ‘database.txt’ file
‘ CheckStudentInformationValid( studentInformation ) ’ is a function from ‘StudentController’ class to check if student information is valid or not. When user want to add new student, they need to enter information of that student, if information is null the program will alert and force user to enter information. Then the program receives that information to check it first if it is unique (except for name and birthday) or valid, if not, program will force user to enter again until that information is unique and valid, after everything is correct, the program will process it by add it to array list and write that array list to file.
B. Delete student:
This is the flowchart of deleting student by id
- Explanation: ‘id.isEmpty() ’ is to check if user entered id. ‘_students.size()’ is the size of the array list.
Then I create the function ‘checkbirthday’ to check the birthday is valid or not, but the when I tried to add birthday with the remaining student information, it appeared the error.
