In this assignment, you are going to simulate a lottery game machine. The goal of the game is for the player to
match as many numbers to the computer’s as possible. To play the game, they have to pay either \$1.00 for one
round or \$5.00 for 5 rounds. Each round ends after the player’s numbers have been compared to the computer’s
numbers. After the number of rounds they paid for or they manually quit the game, the total amount of money
they earned is displayed, and the game goes back to the start menu. The user has 3 options during a round:
Choose Numbers, Check Winnings, and Quit.
If the player selects Choose Numbers, they are given two ways to get their lottery numbers: choosing their own
or quick pick. If they choose their own, they enter 5 different numbers from 1 to 20. There CANNOT be
duplicate numbers. If the player enters the same number twice, they see an error message, and have to enter a
new number. If they choose quick pick, the computer will generate 5 different random numbers from 1 to 20 for
them. There CANNOT be duplicate numbers. The 5 numbers chosen by the player or the computer MUST be
stored in an array.
If the player chooses Check Winnings, the player’s numbers are compared to 5 randomly generated numbers
that are the winning numbers. The winning numbers and the player’s numbers are displayed. Then, it states the
number of matches between the winning numbers and the player’s, displays how much money they won that
round, and how many rounds are left. For each number that matches, the player earns \$10.00. The winnings are
all added to a total that keeps track of how much money has been won altogether.
Player chooses Quit, the current player’s game ends, the total amount of money won is displayed, and then it
goes back to the start menu. This program should only end if you close the .java file. If the player chooses Quit
before they have used all of their rounds, the remaining money they paid to play the game is added to their total
winnings.
Programming Notes:
 You MUST use arrays to store the players 5 numbers and the winning numbers.
 You MUST do input validation for all of the user input.
o Numbers must be integers (no floating-point numbers or words)
 You MUST use exception handling for this.
o Numbers must be in the correct range.
