For validating and parsing a barcode representing a bill, use the parseBarcode() method.

Bill bill = IrBill.parseBarcode("the-string-data-of-barcode") ;

If the barcode contains valid data, the bill object contains information such has billId, paymentId, amount and bill type. Otherwise the bill will be null.

In order to validate and parse billId and paymentId, also known as شناسه قبض and شناسه پرداخت, you can alternatively use the parseBillData method :

Bill bill = IrBill.parseBillData("billId","paymentId");

If the billId and paymentId are valid, the bill object will contain more complementary information such as amount and bill type. Otherwise the bill will be null.

There are also two public utility methods, validateBillId and validatePaymentId, which can come handy for further debugging.

if(IrBill.validateBillId("billId")) ...

if(IrBill.validatePaymentId("billId","paymentId")...

The Bill class has the following field members :

class Bill {

    private BillType type ;
    private String billId ;
    private String paymentId ;
    private long amount ; //in RIALS (IRR)
    
 }   

and the BillType enum contains information on different types of bills and their string representations in Persian and English.

Finally, if the paymentId strings starts with leading zeroes, which is a typical case with bills of all types, all IrBill methods that accept paymentId, either directly or indirectly will take care of the trimming.
