java.util.InputMismatchException when reading from file

Question

I get a java.util.InputMismatchException when I read the following information from a file:

ADDRECORD CPCS-204 289 Rayyan Alzahrani 62 58 76

Student s = null;
while (input.hasNext()) {
    String command = input.next();
    if (command.equals("ADDRECORD")) {
        int ID = input.nextInt();
        String firstName = input.next();;
        String lastName = input.next();
        int[] examGrades = new int[nnmCourses];
        for (int i = 0; i < nnmCourses; i++) {
            examGrades[i] = input.nextInt();
            s = new Student(ID, firstName, lastName, examGrades);
            System.out.print(nnmCourses);
        }

On which line does that error occur? And it's not a compiler error. — Andy Turner

You are calling

input.nextInt()

but the next token after ADDRECORD will be

CPCS-204

You need to read this token first, then read the ID field.

You might find it easier to use input.nextLine(), and then split or otherwise tokenize that string.
