Java implementation from TXT file read input information output QR code

The following source, note do not put in the same folder, choose the Chinese encoding format "Utf-8"

Pay attention to the reading of the string, indicating that the novice to do the first gadget is very excited, although copied some source code, but the sweep out is still very cool
