abhijeet02singh/Student-Result-Calculator — reverse-engineered prompt

Build me a simple Java console program for calculating a student’s result. It should ask for the student name and roll number, then ask for marks in 5 subjects. Each subject should be out of 20, so if someone enters more than 20 or a negative number, ask again until they enter a valid mark.

After all marks are entered, show the total marks, percentage, grade, and a short remark. Use these grades, A for 90 and above with Excellent, B for 80 to 89 with Very Good, C for 70 to 79 with Good, D for 60 to 69 with Average, E for 40 to 59 with Need Improvement, and F for below 40. Also, if the student gets less than 7 in any subject, they should automatically fail no matter what the total is.

Keep it beginner friendly and easy to understand, using Scanner, loops, and simple if else or switch logic.
