UPCABarcode
public UPCABarcode(String data)
throws BarcodeException
- Constructs a basic mode UPC-A barcode with the specified data and an optional
checksum. The length of the barcode is 11, 12 with a checksum. If the length
passed is only 11, then a checksum will be automaticaly added. If the length
is not 11 or 12 then a barcode exception will be thrown.
- Parameters:
data
- The data to encode
- Throws:
BarcodeException
- If the data to be encoded is invalid
