posnet barcodes

Part A: POSNET Bar Codes Goal: Print Address with POSNET bar code. (POSNET means Postal Numeric Encoding Technique.) Here is an example of such an address: We will use the vertical line ( | ) to represent the long bar and semicolon ( : ) to represent the short bar Input File: [login to view URL] (Naming this input file a .csv extension is also okay, but then it opens up in Excel if you double click on its name in the Windows Explorer. Details: 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 Obtain the input file using a JFileChooser dialog. For each line write out an address like this: Anna Lee 123 Nice Street Memphis TN 38141-8346 |::||:|::|::::||:|::|:::|||::|::::||:|::|:||::::|:|| Stan Smith 456 De La Vina Street Santa Barbara CA 93101-3298 ||:|::::||::::||||::::::||::||:::|:||:|::|::|::|::|| 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 Write and use this method: public static String getBarCode(String zipcode) Part B: JFreeChart Graphs These examples are relevent for Part B of Project 3: WriteGreetings (input-output) ReadFromWeb (input-output) BarGraph (jfreechart) Choose five international source currencies to monitor. Each currency is referenced with a three letter ISO 4217 currency code. For example, the code for the U.S. Dollar currrency is USD. Search online for these abbreviations with a search string such as "ISO 4217 Currency Codes." Place these source currencies in a text file. The following URL is a link to a CSV file that contains the exchange rate for a given source and target currency. For example, if the source currency is EUR and the target currency is USD, the URL is [login to view URL] Read the five source currencies in the text file that you created in Step 1, dynamically create URLs that are passed to Java Scanner objects to obtain the exchange rates (to USD) for five source currencies from Part 1. Plot the five exchange rates that you found in Step 2 in a JFreeChart bar chart. See the BarChart Example in the jfreechart example file. Your Java project should contain only a single class, which contains the main method. This class must define at least three additional static methods that modularize the tasks in this project. For example, you might define methods such as these: public static String getCurrency(Scanner s) public static String getURL(String sourceCurrency, String targetCurrency) public static double getExchangeRate(String url)
