Goal: Print Address with POSTNET bar code. (POSTNET means Postal Numeric Encoding Technique.) Here is an example of such an address: We will use the vertical line ( | ) to represent the long vertical bar and semicolon ( : ) to represent the short vertical bar

Input File: addresses.txt (Naming this input file with a .csv extension is also okay, but then it opens up in Excel if you double click on its name in the Windows Explorer.)

addresses.text looks like this:

Anna Lee,123 Nice Street,Memphis,TN,38141-8346 Stan Smith,456 De La Vina Street,Santa Barbara,CA,93101-3298 Meredith Baker,1343 Maple Avenue,Denver,CO,80236-2982 Julia Chen,336 Euclid Avenue,Cleveland,OH,44120-4321 Jason Sanchez,4320 West Diversey Avenue,Chicago,IL,60738-7609

Details:

1. Read an input CSV file containing addresses using a Scanner object. Don't redirect from stdin, read directly from the file. Here are two sample lines from a mailing list:

   Anna Lee,123 Nice Street,Memphis,TN,38141-8346 Stan Smith,456 De La Vina Street,Santa Barbara,CA,93101-3298 

2. Obtain the input file using a JFileChooser dialog. See the UseFileChooser Example in the input-output examples file.

UseFileChooser Example looks like this:

import java.io.*; import java.util.Scanner; import javax.swing.JFileChooser; public class UseFileChooser { public static void main(String[] args) throws FileNotFoundException { // Open file containing names with FileChooser dialog JFileChooser chooser = new JFileChooser( ); chooser.showOpenDialog(null); File fileObj = chooser.getSelectedFile( ); // Read names and write greetings, each in their own file. Scanner in = new Scanner(fileObj); while (in.hasNextLine( )) { String name = in.nextLine( ); String greeting = "Hello " + name + ", how are you?"; PrintWriter pw = new PrintWriter(name + ".txt"); pw.println(greeting); pw.close( ); } in.close( ); } }

1. For each line write out an address like this to the output file labels.txt:

   Anna Lee 123 Nice Street Memphis TN 38141-8346 |::||:|::|::::||:|::|:::|||::|:::||::|::|:||::::|:|| Stan Smith 456 De La Vina Street Santa Barbara CA 93101-3298 ||:|::::||::::||||::::::||::||:::|:||:|::|::|::|::|| 

2. The bar code is encoded using this table:

   1	2	3	4	5	6	7	8	9	0
   :::||	::|:|	::||:	:|::|	:|:|:	:||::	|:::|	|::|:	|:|::	||:::

   In addition to encoding the 9 digits of the zip code, the bar code includes initial (i) and terminal (t) frame bars and a check sum (cs), which is 10 - the sum of the zip code digits mod 10. Thus the zip code 38141-8346 is encoded like this:

   i 3 8 1 4 1 8 3 4 6 cs t | ::||: |::|: :::|| :|::| :::|| |::|: ::||: :|::| :||:: ::|:| | 

   The sum of the digits is 38 and 38 % 10 is 8, so the check sum is 10 - 8 = 2. The initial and terminal frame bars are always |. Note: If the sum of the digit % 10 is 0, the check sum is 10 - 0 = 10, which should be replaced by 0. This can be done with an if statement, or with

   checksum %= 10 

   Putting this together, you can compute the checksum like this:

   checksum = (10 - sumOfDigits % 10) % 10

3. Write and use this method:

   public static String getBarCode(String zipcode)
