I am supposed to use an interface GradeMapper. ClassicRubric and TriageRubric are the different grading scales that i'm using to test this ability. I managed to get those 3 classes working without errors.
However once i get to the driver Class I run into a lot of problems.

Code:

public class ClassicRubric implements GradeMapper{
    
    public String toLetter(double percent){
        if (percent >= .9)return "A";
        
        else if (percent >= .8)return "B";
        
        else if (percent >= .7)return "C";
        
        else if (percent >= .6)return "D";
    
        else return "F";
    }

}

Code:

public class TriageRubric implements GradeMapper{
    
    public String toLetter (double percent){
        
        
        if (percent > 17.0/18.0){
            return "A";}
        
        else if ((percent >8.0/9.0)){
           return "A-";}
      
        
        else if(percent>5.0/6.0){
           return "B+";
        }
        
        else if(percent>7.0/9.0){
            return "B";
        }
        
        else if(percent>13.0/18.0){
            return "B-";
        }
        
        else if(percent>2.0/3.0){
           return "C+";
        }
        
        else if(percent>3.0/5.0){
           return "C";
        }
        
        else if((percent>8.0/15.0)){
           return "C-";
        }
        
        else if((percent>7.0/15.0)){
            return "D+";
        }
        
        else if(percent>2.0/5.0){
            return "D";
        }
        
        else if((percent>3.0)){
            return "D-";
        }
        
        else {
            return "F";
        }
        
    }
        
}

Code:

public interface GradeMapper {
    
    public String toLetter(double percent);

}

i

Code:

mport java.util.Scanner;

public class Driver {
    
    public static void main{
        
        double pointsEarned;
        double totalPoints;
        int gradingType;
        double percent;
           
        System.out.println("input total points");
            
        Scanner input = new Scanner(System.in);
        
        totalPoints = input.nextInt();
        
        System.out.println("input the number of points you earned");
        
        pointsEarned = input.nextInt();
        
        System.out.println("For triage type 1 for classic type 2");
        
        gradingType = input.nextInt();
        
        percent = pointsEarned/totalPoints;
        
        if (gradingType = 1){
            
            new TriageRubric(GradeMapper(percent));
        }
        
        if (gradingType = 0){
            new ClassicRubric(GradeMapper(percent));
        }     
        
    }

}

the bolded places are where i get errors. How do i make it so that if the user enters 1 then he gets the TriageRubric that uses the "percent" variable? and if he enters 0 he gets the ClassicRubric that uses the "percent" variable.

also how do i tell it to print out the result to the screen?
Thanks
