Programming assignment

1. You will be designing / implementing the completion of a Program that simulates the QuickPick function at a local convenience-store when selling Lottery Game Tickets such as

Lotto, MegaMillons, Daily Number, PowerBall, etc.

You will need the services of the already implemented Class called the Randomizer - specifically, the generateInt() method which has the following signature:

/** Returns a random integer value between the values passed in as arguments high and low inclusive of. So invoking generateInt(100, 200) might return 100, or 200 or any value between

*/

int generateInt(int low, int high){ }

2. Review the code of the stubbed out edu.cuny.csi.csc330.lab3.LottoQuickPicker

Finish the implementation of this Class given the following requirements reviewed in class:

1. Needs to generate 1 or more quick pick game (one by default overridden by an optional command line argument).

2. For each game:

1. Generate 6 unique numbers between 1 and 59.
2. The Class is responsible for displaying the game ticket as described below (see actual example below as well).
   1. The unique numbers for each game must be sorted in ascending order on the same horizontal line.
   2. The Game Ticket should display a game specific heading including a date/time.
   3. Each game will be numbered/indexed 1,2,3, N
   4. Game numbers will be evenly spaced /formatted. And single digit numbers will be padded with a leading 0.
   5. The Game Ticket should display both a header and trailer of your own choosing (see general format and sample displayed ticket below).

• How would you calculate the odds of customer winning a single purchased Lotto Game? Well, what are the odds of picking 6 randomly selected numbers out of a pool of 59 numbers? Research the mathematical solution, and code it in the calculateOdds() method - and display the value returned by this method as shown above.
• NOTE:
  • Your solution should work for any game specification not just 6 of 59.
  • To get full [10 points] credit, describe your solution in comment block above the calculateOdds() method.
