WELCOME TO TARIQ'S PainfullAfternoon (Hurtlocker.JerkSON)

  • Objective: To implement a GroceryReporter capable of parsing JerkSON and formatting to a string
  • Purpose: To gain familiarity with regex and payload parsing

You will need all of these today!

In this project you will find a file in the resource directory named RawInput.JerkSON. It was supposed to be a grocery list formated in JSON. However, Tariq, your fearless yet petty leader decided to come reformat it in his own Object Notation. JerkSON... you are welcome.

JSON Format

  • In JSON,
    • keys are encapsulated by quotes
    • values are encapsulated by quotes (unless numeric)
    • key and value are seperated by a colon.
    • key and value pairs are seperated by a comma.
{
  "name" : "Milk",
  "price" : 3.25,
  "type" : "food",
  "expiration" : "01/24/2016" 
}

JerkSON Format

  • Just like JSON, JerkSON is a key-value-pair-data-store.
  • In JerkSON,
    • key and value are seperated by any of the following (:, @, ^, *, %)
    • key and value pairs are seperated by a ;.
    • objects are separated by ##
NaMe:egGS;[email protected];typE^foOd;eXPiRAtIOn%1/24/2016##

Some tidbits

All string manipulation should be achieved through regex to detect and match patterns. Its not guaranteed that every Key will have a Value, and every Value will have a pair. For instance:

you may see something like this Name:Milk;Price:3.23;type:;expiration:1/24/2016##

Notice how TYPE has a key but no Value.... if you try and parse this into an object your program could crash. You will need to handle your exceptions! I also expect you to report on how many exceptions you saw while parsing the data. Write a few tests, for each "sub stage" of your code.

And then finally, for each grocery item, built a quick text output of High/Low and and Average value for the things on the list. GOOD LUCK ZIPCODERS!!!! May the Odds be ever in your favor!!!!
