Create a program to decide students grade as follow 90 100

Create a program to decide students grade as follow:

90 - 100 = A

80 - 89 = B

70 - 79 = C

60 - 69 = D

0 - 59 = F

Make sure that no grade can go above 100, nor below 0.

You must allow users to enter the values using (Scanner).

Solution

StudentGrades.java

import java.util.Scanner;

public class StudentGrades {

   public static void main(String[] args) {
       Scanner scan = new Scanner(System.in);
       int grade;
       char gradeLetter;
       do{
           System.out.print(\"Enter student grade between 0 and 100: \");
           grade = scan.nextInt();
       }while(grade <0 || grade >100);
       if(grade >90 && grade<=100){
           gradeLetter = \'A\';
       }
       else if(grade >=80 && grade<90){
           gradeLetter = \'B\';
               }
       else if(grade >=70 && grade<80){
           gradeLetter = \'C\';
       }
       else if(grade >=60 && grade<70){
           gradeLetter = \'D\';
       }
       else{
           gradeLetter = \'F\';
       }
       System.out.println(\"Grade latter is \"+gradeLetter);
   }
  

}

Output:

Enter student grade between 0 and 100: 81
Grade latter is B
