String randomIban1=randomIBAN.generate(); 
String randomIban2=randomIBAN.generate();
String randomIban3=randomIBAN.generate();

Sample Example to test valid Iban and uniqueness of the generated IBAN:

RandomIBAN.isValid("DE89370400440532013000"); //to test valid

ArrayList<String> uniqueIbans = new ArrayList<>(); // to test uniqueness random iban
RandomIBAN randomIBAN_NL = CountriesIBANFormat.getInstance().getIbanFormatByCountry("NL");
        for (int i = 0; i < 100; i++) {
            String iban = randomIBAN_NL.generate();
            System.out.println("iban : " + iban +" isValid : "+RandomIBAN.isValid(iban));
            
            if (uniqueIbans.contains(iban)) {
                System.out.println("Ouups iban already exists ... ");
            }
            uniqueIbans.add(iban);
