using a loop to validate you id is valid ,that is a code

   public static void main(String[] args) {
        Scanner scanner=new Scanner(System.in);
        boolean ifValid=false;
        String ID;
        //using loop to validate this id is valid and length is 8
        do{
            System.out.print("Please enter your ID : ");
            ID = scanner.nextLine();
            ifValid= validateID(ID, salespersons);
            if (!ifValid){
                System.out.print("Duplicate digits. Please enter eight digits of your ID : ");
            }
        }while (!ifValid);
        System.out.print("Please enter eight digits of your ID : ");
        ID = scanner.nextLine();
    }

    private static boolean validateID(String id, Object salespersons) {
        return id!=null&&8==id.length();
    }
