Hi,
Kindly help me about this coding. Could any one update me back if any suggestions or improvements are required.


Using core java application to generate a QR(Quick Response) code based on a file which will contains characters. After generating code it should print the barcode image. The image size can also be parameterize.

The file will contain 6 fields, each field will have a 30 characters.

text format in file will be as follows

abcdefghijklmnopqrstuvwxyz1234abcdefghijklmnopqrstuvwxyz1234abcdefghijklmnopqrstuvwxyz1234abcdefghijklmnopqrstuvwxyz1234abcdefghijklmnopqrstuvwxyz1234abcdefghijklmnopqrstuvwxyz1234

in above text form a to 4 field one, again from a to 4 field 2 and so on.
Read the above text and generate QR code and images.
