Easy-to-Use School Management System

Teacher Student

This is my first Java project that gives simple features depending on your chosen role. Choosing the role of a teacher allows you to manage your students and give them grades. On the other hand, the role of a student allows you to manage your grade book and calculate your weighted average grade. This project was inspired by what I have learned from the University of Helsinki's MOOC.fi Java Programming I and II which led to the creation of this project. Furthermore, I created this project to better understand object-oriented concepts such as Abstraction, Inheritance, Polymorphism, and Encapsulation and how they make relationships with each other.

Getting Started

To launch the program, follow these simple steps

1. Go to src folder.
2. Open the Main.java file.
3. Make sure that the following code is present

   public class Main
   {
       public static void main(String[] args)
       {
           UserInterface ui = new UserInterface();
           ui.start();
       }
   }

4. Run the Main.java to execute the program.

Functionality

Once the program is running, you can freely explore the following features you can find depending on which role you chose.

👩‍🏫 Features available for teacher role

1. Store class list - saves class list either
   • processing a file, or
   • manually inputting the names and student numbers of the student one by one
2. Display class list - displays class list only if
   • the class list is stored, or
   • a new student is added
3. Delete class list - empties the students' information stored in the class list
4. Find a student - finds a student through
   • their last name, or
   • student number
5. Add a new student - adds a new student even if the class list is empty or not
6. Remove an existing student - removes an existing student from a class list
7. Store grades - stores grades either
   • processing a class list with their corresponding grade but only one subject, or
   • manually inputting the grades of each student but can store multiple and varying subjects
8. Display class grade book - displays grade book if you have successfully
   • process the grade book, or
   • manually input grades
9. Delete class grade book - empties the grades stored in the grade book

🧑‍🎓 Features available for student

1. Store grades - save grades either
   • processing a file, or
   • manually inputting the subject, grade, and unit one by one
2. Display grades - displays the grades only if a list of grades is stored
3. Delete my grade book - empties the student's grade book
4. Compute my general weighted average - calculates the total general weighted average
   • Grade Point Range (1.00 - 5.00 with a step of 0.25)
   • Calculation
     • Variables:
       • GWA: General Weighted Average
       • Grade: Grade obtained in each subject
       • Unit: Unit or weight of each subject
     • Formula:
       • GWA = Summation of (Grade × Unit) / Summation of Unit
       • GWA = ((Grade1 × Unit1) + (Grade2 × Unit2) + ... + (GradeN × UnitN)) / (Unit1 + Unit2 + ... + UnitN)
5. Find grade - finds grades either
   • subject name, or
   • subject unit

📘 Creating class list and grade book

1. Format Requirements:
   • Despite that, there is a ready-to-made class list and grade book, you can still create your own file. However, there is a following format that must be followed so that it can be read and processed. The data is cleaned by separating values using the Comma-Separated Values (CSV) format. The following format is used for:
   • Teacher
     • Class List
       • FirstName, LastName, StudentNumber
     • Grade Book (can also be used as a class list)
       • FirstName, LastName, StudentNumber, Grade
   • Student
     • Grade Book
       • SubjectName, Grade, Unit
2. Location:
   • Create the file within the project folder named Easy-to-Use School Management System. Ensure that you create the file inside this project, or else it will throw a java.io.FileNotFoundException: File not found. Please try again
   • Within the project folder named Easy-to-Use School Management System, you can see pre-existing files named
     • Student_A_Grades
     • Teacher_A_ClassList
     • Teacher_A_GradeBook
   • You can even check the following files mentioned and follow how they are formatted for your reference.
3. Creating a new file:
   • Within that section, right-click your mouse and select New and give your file a descriptive and meaningful name.
   • Then input your data according to the format requirements.
