Hi,
Plz help me out from this problem. I have already developed the coding but i faced only
one problem i am not getting All the six fields should come one by one. One field in one
Line. Kindly help me...Plz..Plz...

Develop a new 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 and All the six fields should come one by one. One field in one line.

and the The basic requirement is:

Input data:

Field1 - Building Number : 8 digits [Numeric]
Field2 - Street Name: 30 Characters [Char]
Field3 - District name: 30 Characters [Char]
Field4 - City name: 30 Characters [Char]
Field5 - Zip Code: 6 digits [Numeric]
Field6 - Additional Number: 30 Characters

So, your input data file will look as per the following:

Field1, Field2, Field3, Field4, Field5, Field6
Field1, Field2, Field3, Field4, Field5, Field6
Field1, Field2, Field3, Field4, Field5, Field6
Field1, Field2, Field3, Field4, Field5, Field6
Field1, Field2, Field3, Field4, Field5, Field6
Field1, Field2, Field3, Field4, Field5, Field6
Field1, Field2, Field3, Field4, Field5, Field6

Output would be,

QR code

The property file should contain (all parameters required to read the file, size of the QR code etc):

From which path the java program should read the input data file
What is the size (dimension) of the QR code
Output file path, etc.

My Coding is that
