package Grade;

import java.util.Scanner;

public class grade {
    public static void main(String[] args){

        System.out.println("Welcome to the Letter Grade Converter");
        System.out.println();
        
        Scanner sc = new Scanner(System.in);
        
        String choice = "y";
        while (choice.equalsIgnoreCase("y")){
            
            System.out.println("Enter numerical grade: ");
            int grade = sc.nextInt();

            char letter = 0;

            if(grade <= 100 || grade >= 88)
                letter = 'A';
                System.out.println("Your Grade is: " + letter);

            if (grade <= 87 || grade >= 80)
                letter = 'B';
                System.out.println("Your Grade is: " + letter);
            
            if (grade <= 79 || grade >= 67)
                letter = 'C';
                System.out.println("Your Grade is: " + letter);
            

            if(grade <= 66 || grade >= 60)
                letter = 'D';
                System.out.println("Your Grade is: " + letter);
            

            if(grade <= 60)
                letter = 'F';
                System.out.println("Your Grade is: " + letter);

            System.out.println("Continue? (y/n): ");
            choice = sc.next();
            System.out.println();

        }

    }

}

I'm trying to get only one letter grade, plus instead of 'F' I'm getting 'D'.
Any help would be really appreciated.
Thanks

you are in the wrong forum :) this is javascript forum, not java :)

Use a switch statement instead:
switch(grade)
{
case(grade<100 && grade>90):System.out.println("Your grade is A"); break;
case(grade<90 && grade >80):System.out.println("Your grade is B"); break;
...
default:System.out.println("Failed");
}
Essentially, a switch statement grabs a variable (in this case grade) and compares it against numerous cases. If a case is met, it will run the code after the : character. In no other cases are met, it will run the default code (in this case, fail). The break will move to match the grade to the next case, so make sure that is included. This is much better than having numerous if-else statements. Hope this helps
