This is the question - Write an application that displays a series of at least eight student ID numbers (that you have stored in an array) and asks the user to enter a test letter grade for the student.

Question

This is the question -

Write an application that displays a series of at least eight student ID numbers (that you have stored in an array) and asks the user to enter a test letter grade for the student.

Create an Exception class named GradeException that contains a static public array of valid grade letters (A, B, C, D, F, and I) that you can use to determine whether a grade entered from the application is valid. In your application, throw a GradeException if the user does not enter a valid letter grade. Catch the GradeException, and then display the message Invalid grade. In addition, store an I (for Incomplete) for any student for whom an exception is caught. At the end of the application, display all the student IDs and grades.

Code I was given, I will attach a screenshot of the errors-

public class GradeException extends Exception {

public GradeException(String string) {

}

import java.util.*;

public class TestGrade {

public static void main(String args[]) throws Exception {

Scanner input = new Scanner(System.in);

int[] ids = { 1234, 1245, 1267, 1278, 2345, 1256, 3456, 3478, 4567, 5678 };

char[] grades = new char[10];

String gradeString = "ABCDFi";

final int HIGHLIMIT = 100;

String inString, outString = "";

int flag = 0;

for (int x = 0; x < ids.length; ++x) {

System.out.println("Enter letter grade for student id number: " + ids[x]);

inString = input.next().toUpperCase();

grades[x] = inString.charAt(0);

if (!gradeString.contains(grades[x] + "")) {

try {

throw new GradeException();

} catch (GradeException e) {

System.out.println("Invalid grade");

grades[x]='I';

}

for (int x = 0; x < ids.length; ++x)

outString = outString + "ID #" + ids[x] + " Grade " + grades[x] + "\n";

System.out.println(outString);

}
