SGPA Calculator

SGPA This is a Java program that calculates your Semester Grade Point Average (SGPA) based on the grades and credits of the subjects you have taken in a semester.Additionally, it provides a feature to save the calculated SGPA and inputted marks to a file.

How to Use

  1. Open the terminal or command prompt.
  2. Navigate to the directory where the program is saved.
  3. Compile the program using the command javac SGPA.java.
  4. Run the program using the command java SGPA.
  5. Enter the number of subjects you have taken in the semester.
  6. Enter the grade and credits of each subject when prompted.
  7. The program will display your SGPA.
  8. The program will also save the entered data and SGPA to a file named [Name]_sgpa_data.txt (e.g., John_Doe_sgpa_data.txt).

Grade Point Scale

This program uses the following grade point scale:

Grade Grade Point
A+ 10.0
A 9.0
B+ 8.0
B 7.0

If your university uses a different grade point scale, you can modify the getGradePoint() method in the program to match your university's scale.
