Question

Complete the program, Grade.java, below. The program takes in a student's score and prints the corresponding letter grade assuming a standard 60-70-80-90 scale for cutoff of each grade. For example, if a student's score is 52.6 they would be assigned an "F" grade. If a student's score is 87.8 they would be assigned a "B grade.

The program should take in the score as a double value and print the letter grade (capitalized letter of A, B, C, D, or F). You may assume that all scores will be in the range 0 to 100.

import java.util.Scanner;

public class Grade {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
System.out.println("Enter the student's score:");
//TODO: complete the program
  
}
}

Answer 1

import java.util.Scanner;

public class Grade {
    public static void main(String[] args) {
        Scanner scnr = new Scanner(System.in);

        // Reading score from user
        System.out.println("Enter the student's score:");
        double score = scnr.nextDouble();

        System.out.print("Grade: ");
        // Checking if score is less than 60
        if(score<60){
            System.out.println("F");
        }
        // Checking if score is less than 70
        else if(score<70){
            System.out.println("D");
        }
        // Checking if score is less than 80
        else if(score<80){
            System.out.println("C");
        }
        // Checking if score is less than 90
        else if(score<90){
            System.out.println("B");
        }
        // Checking if score is less than 100
        else {
            System.out.println("A");
        }
    }
}

Output:

Enter the student's score: 87.8 Grade: B Process finished with exit code 0
