Scanner exception in a biggner project (student management app)

Question

I am a beginner in java and I am trying to do this simple project, which is an app that adds new student to the school system, I am having a problem in a method "courses", this methods have to return a String with the courses the user picked (first they are stored in a list, then with the help of Arrays.toString they are converted to a string. so how you can sees from the code the user inter the number of the courses and that number saved in variable n then a list being created with that length, then inside the loop the student choose what courses. the program works half through then shows errors :

public String courses() {
            int k;
            Scanner inpot = new Scanner(System.in);
            System.out.println("How maney courses do u want to enroll in ?");
            int n = inpot.nextInt();
            String[] courses = new String[n];
            System.out.println("choose the courses");
            System.out.println("\n 1 : Math \n 2 : History \n 3 : computer scince \n 4: lecture");
            
            for(int i = 0; i < n ; i++) {
                 k = inpot.nextInt();
                if(k == 1) {
                    courses[i] = "math";
                }
                else if(k == 2) {
                    courses[i] = "History";
                }
                else if( k == 3) {
                    courses[i] = "Computer scince";
                }
                else if (k == 4) {
                    courses[i] = "lecture";
                }
                
                System.out.println("your couse number " + (i + 1) + " has been saved");
                
                if((i+1 == n)) {
                    System.out.println("you enterd all the courses");
                    
                    
                }
                else {
                System.out.println("enter your next cours");
                }

            }
            inpot.close(); 
            
            return Arrays.toString(courses);
        }

Here is also the other class that have main in it

public class Studentdatabase {

    public static void main(String[] args) {
        
        
        
        Student s1 = new Student("Lucas", "Moller", 8); 
        
        String m = s1.courses();
        System.out.println(m);

    }
