2) Declare variable total and percentage

3) Create Scanner object and prompt the user to enter grades for each class and input grades after each class

4) Calculate total of all classes

5) Calculate Percentage where total is divided by 500 and then multiplying by 100.

Answer #1

Solution:

import java.util.*;

Class StudentGrades {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

int English, Chemistry, Java, Physics, Maths, total = 0, percentage = 0;

System.out.println("Enter English grade: ");

English = sc.nextInt();

System.out.println("Enter Chemistry grade: ");

Chemistry = sc.nextInt();

System.out.println("Enter Java grade: ");

Java = sc.nextInt();

System.out.println("Enter Physics grade: ");

Physics = sc.nextInt();

System.out.println("Enter Maths grade: ");

Maths = sc.nextInt();

total = English + Chemistry + Java + Physics + Maths;

percentage = (total/500)*100;

if(percentage >= 90) {

System.out.println("A Grade:);

} else if(percentage >= 80 && percentage < 90) {

System.out.println("B Grade");

} else if(percentage >= 70 && percentage < 80) {

System.out.println("C Grade");

} else if(percentage >=60 && percentage < 70) {

System.out.println("D Grade");

} else if(percentage >=50 && percentage < 60) {

System.out.println("E Grade");

} else {

System.out.println("F Grade");

}

System.out.println("Total points :" + total);

System.out.println("Average score: " + total/5);

return;

}

}
