Question

java/javafx assignment:

Island Paradise just started running their city lotto. You've been tasked with writing a program for them. The program is going to allow to user to first select their lotto numbers. The program will then randomly generate the winning lotto numbers for the week and then check the winning numbers against the random ticket the user played in the Lotto to see how many numbers the user guessed correctly.
The rules for lotto work as follows:
Select 7 numbers between 1 and 50
Twice every week 7 numbers are drawn at random
If a player matches all 7 numbers they win a million dollar prize
If a player matches 6 numbers they win $100,000
If a player matches 5 numbers they win $5,000
If a player matches 4 numbers they win $100.
If a player matches 3 numbers they win a free ticket.
Your program should work as follows. (NOTE:  I have listed some functions you need to include in your program – you may include other functions if you would like and they make your program more readable/efficient).
Step 1
Create an array named UserTicket to hold each of the user’s lotto number selections.
Create an array named WinningNums to hold the winning lotto numbers.
Step 2
Display the following menu:
ISLAND PARADISE LOTTO MODEL:
--------------------------------------------------
1) Play Lotto
q) Quit Program
Please make a selection:
If the selection is 1:
a. First ask the user their name and store it in an appropriate variable.
b. Next, call a function named getLottoPicks that asks the user to enter their 7 lotto number picks (selections) for the week. Each of the user’s lotto picks should be stored in the userTicket array. The lotto does NOT have duplicate numbers in it. Find a way to not allow duplicate numbers to be picked by the user. You may want to create another function called noDuplicates that checks to see if the user’s selection is already in the userTicket array. If the user enters a number already in the array, ask them to enter another number until they enter one that is not a duplicate.   This means the UserTicket array should contain no duplicate numbers.
c. Next, call a function named genWinNums that randomly generates the winning lotto numbers for the week based on the rules stated above and stores the winning lotto numbers in the winningNums array (so you are going to fill the winningNums array with random numbers between 1 and 50). Do not allow this function to generate duplicate winning numbers (if you design your noDuplicates function above well you should be able to re-use it to check for duplicates in the winningNums array).
HINT: There are two ways to avoid having duplicate numbers in an array. The first method is to check the array after each number is generated or entered to make sure that number is not already in the array. If the number generated/entered is already in the array a new number should be generated/entered. The second method involves sorting and checking that the numbers next to each other in the array after the sort are not the same.
d. The next step is to check the user’s lotto ticket (represented by the UserTicket array) to see if they have won any prizes in the Lotto game. Check each number the UserTicket array to see if that number is in the winningNums array and count how many numbers are matched.
Output
Display a report similar to the following showing user’s lotto results – the example output below assumes the user entered a name of “Alex” when the program started.
In the “Winnings” section of the report
Display: JACKPOT!!! - $1 MILLION if all 7 numbers were correct
Display: GREAT! - $100,000 if 6 numbers were correct
Display: LUCKY YOU! - $5,000 if 5 numbers were correct
Display: NOT BAD - $100 if 4 numbers were correct
Display: FREE TICKET if 3 numbers were correct
Display: SORRY NOTHING if 2 or less numbers were correct
Sample Output:-
ALEX'S LOTTO RESULTS
WINNING NUMBERS: 35 03 01 15 10 25 22
ALEX’S TICKET: 33 15 02 06 21 20 19
RESULTS:
You must show report.txt how you program runs exactly.
Number Matches: 1         
Winnings      : SORRY NOTHING
If the selection is q: Quit the program
If the selection is not q and not 1: Display an invalid selection message
Allow the user to play lotto as many times as they would like.
