A QR code string is just a sequence of bytes, like anything else in memory. So what exactly is your problem?

I have trouble encoding a qr code string into base 64 string. Is it possible through any of the Java classes ?

What sort of trouble? As I already said, a QR string is just the same as any other string in Java.

Can you provide me code examples of generating a QR code string instead of a QR code image ?
