Question

Write a method with the following header:

public static char calculateLetterGrade(int grade, int totalMarks)

This method calculates grade/totalMarks and returns a letter grade based on the following scale:

0-50 = F

51-60 = D

61-70 = C

71-80 = B

81-100 = A

Answer 1

Code:

class Main
{
    public static char calculateLetterGrade(int grade, int totalMarks)  //it will return grade based on total marks
    {
        if(totalMarks>=81 && totalMarks<=100)    //if marks in between of 81-100 then grade is A 
        {
            return 'A';
        }
        else if(totalMarks>=71 && totalMarks<=80)  //if marks in between of 71-80 then grade is B 
        {
           return 'B';
        } 
        else if(totalMarks>=61 && totalMarks<=70) //if marks in between of 61-70 then grade is C 
        {
            return 'C';
        }
        else if(totalMarks>=51 && totalMarks<=60) //if marks in between of 51-60 then grade is D
        {
            return 'D';
        }
        else if(totalMarks>=0 && totalMarks<=50) //if marks in between of 0-50 then grade is F 
        {
            return 'F';
        }
        return '0';                           
    }
    public static void main(String args[])
    {        
        System.out.println("Grade of marks 90 is: "+calculateLetterGrade(1,90));
        System.out.println("Grade of marks 80 is: "+calculateLetterGrade(2,80));
        System.out.println("Grade of marks 64 is: "+calculateLetterGrade(3,64));
        System.out.println("Grade of marks 57 is: "+calculateLetterGrade(4,57));
        System.out.println("Grade of marks 45 is: "+calculateLetterGrade(5,45));  
    }
}

Output:
