Hello everyone,

Java Program to Calculate Grade of Students

so friends, (Calculate Grade of Students)in this java program, we will show you student percentage and grade here we using import java util scanner, and also subject enter by the user. first of all, open your NetBeans   or notepad on your PC

And we grade as well as percentage, Here we will take import java util scanner. And after that, we will again create a class by any name. After that, we will add the main class. After that, we’ll take three variables for the student’s subject. And take two variables separately for total and percentage. After that, we will total the three subjects and divide them by three for a percentage

Then we will give a percentage-wise grade to everyone using the switch case. We will put students above 80 percent in A+, grade, And put those between 70% and 80% in one grade. And we will fail those who have 30 percent
