I'm having some trouble with my loop here, I want the user to be able to add more info(the grade and credits) if they have more classes to add. I'm stuck and hoping someone can help. Thanks.
import java.util.*;
public class DoWhileDemo 
{
    public static void main(String[] args){
        String name;
        String add;
        double gradePoints = 0;
        double credits = 0;
        Scanner input = new Scanner(System.in);
        System.out.println("Enter Students Name: ");
        name = input.nextLine();
        do {
            System.out.println("Enter class credits: ");
            credits = input.nextDouble();
            System.out.println("Enter letter grade: ");
            gradePoints = input.nextDouble();
            System.out.println("Add another class? (Y/N) ");
            add = input.nextLine();
        } while (add == ("Y"));
    }
}
