    Default Scanner problem

     
    import java.util.Scanner;
    public class RecordingCalculating
    {
        public static void main(String[] args){
          Scanner sc = new Scanner(System.in);
     
          System.out.println("Student Number: ");
          String numberEntered = sc.nextInt();
          numberEntered = numberCheck(numberEntered, sc);
     
          System.out.print("Family name: ");
          String familyName = sc.nextLine();
     
          System.out.print("First Name: ");
          String firstName = sc.nextLine();
     
     
     
        }

    Clear the scanners buffer after you read a number.

    // read a number

    sc.nextLine(); // clear buffer

    // read a String
