Generate barcode from a string in java

17 New Member
Hello
I have a table of players, each player in the team should have unique barcode:



The barcode scanner returns an array of chars.
The next player_id = char++, example:
aaa
aab
aac
...
aba
aca
..
baa


Or muybe another solution?

Both UPC and EAN barcodes encode just sequences of digits; which encoding do you have in mind?

kind regards,

Thanks but i am sorry to say I don't understand your response.
I asked what should I do to generate a barcode on basis of an array of chars?

All I know is when I take the barcode reader and scan a barcode, the output is like this in (player_id)

I don't think that barcode reader gives your (16 bit or utf-8) chars; it just gives you bytes. Read those bytes and use them as a unique id.

Thank you, that is what I also do, the string or bytes I get as return value when I read a barcode with barcode reader, I use it as unique id.

I am now looking for a good working solution on how to generate a barcode which gives you the code (bytes for example) you have in the table as unique id.

I don't understand what you want then; you have a unique key (a byte[] array) produced by your barcode reader; you have your data that belongs to that key so what other key do you want?

kind regards,

That's easy; there are numerous packages available that can print barcodes for you; google for "print barcode Java" and see for yourself.

kind regards,
