student result management system in java
introduction
The student result management system in java is a robust Java application with a graphical user interface (GUI) that helps manage student data within an educational institution.
Admins can add, view, edit, or delete student records including name, roll number, department, year of study, and academic performance. The system ensures easy navigation through menus and buttons, making it beginner-friendly.
Features include student search, grade calculation, attendance tracking, and record export options. By automating manual processes like record keeping and performance tracking, the system improves accuracy and accessibility.
It is especially useful in schools, colleges, and coaching centers that require a simple yet effective way to manage student information.
steps to create student result management system in java

code explanation
1. Login Panel
Basic login screen.
Accepts a username and password.
If username =
"admin"and password ="1234", it opens the main panel.Otherwise, it shows an “Invalid credentials” message.
2. Main Panel (After Login)
Inputs:
nameField→ Student's NamerollField→ Roll NumbermathField,scienceField,englishField→ Marks input fields
Buttons:
Calculate Result→ Computes total, percentage, and result.Save Result→ Saves result to a file.View All Results→ Reads and shows all saved results from the file.
Text Area:
resultArea→ Displays the calculated result (total, percentage, and pass/fail).
Key Methods Explained:
🔹 calculateResult()
Reads marks from the fields.
Calculates total marks, percentage, and checks if percentage ≥ 40% (Pass).
Shows the result in the
resultArea.
🔹 saveResult()
Saves student name, roll no, and result into a text file called
results.txt.Checks if all fields are filled first.
Appends data to the file.
🔹 viewResults()
Reads all results saved in
results.txt.Displays them in the
resultArea.
🔹 clearFields()
Clears all input fields after saving.
How to Run It:
Compile and run the program.
On the login screen:
Username:
adminPassword:
1234
After logging in:
Enter name, roll no, and marks.
Click
Calculate Result.Then click
Save ResultorView All Results.
