Explanation:

import java.util.Scanner;

public class KboatStudentGrades

{

public static void main(String args[]) {

Scanner in = new Scanner(System.in);

System.out.print("Enter name of student: ");

String n = in.nextLine();

System.out.print("Enter class of student: ");

int c = in.nextInt();

System.out.print("Enter roll no of student: ");

int r = in.nextInt();

System.out.print("Enter marks in 1st subject: ");

int m1 = in.nextInt();

System.out.print("Enter marks in 2nd subject: ");

int m2 = in.nextInt();

System.out.print("Enter marks in 3rd subject: ");

int m3 = in.nextInt();

System.out.print("Enter marks in 4th subject: ");

int m4 = in.nextInt();

System.out.print("Enter marks in 5th subject: ");

int m5 = in.nextInt();

int t = m1 + m2 + m3 + m4 + m5;

double p = t / 500.0 * 100.0;

String g = "";

if (p >= 90)

g = "A+";

else if (p >= 80)

g = "A";

else if (p >=70)

g = "B+";

else if (p >= 60)

g = "B";

else if (p >= 50)

g = "C";

else if (p >= 40)

g = "D";

else

g = "E";

System.out.println("Total Marks = " + t);

System.out.println("Percentage = " + p);

System.out.println("Grade = " + g);

}

}
