Please just focus on these main topics. We haven't learned anything past these topics. It can not have any complex things in it. Thanks!!

Program Specification:

Write a Java program that allows the user to play roulette. In our version of roulette, the roulette wheel has the following characteristics:

Slots are numbered from 0 to 36 Even numbered slots are colored Red Odd numbered slots are colored Black The 0 slot is colored Green

The user starts with 100 chips, and each round can place one the following two types of bets - or quit (cash out):

Bet on a specific number [0, 36] (payout is 35:1) Bet on either Red or Black color (payout is 1:1) Cash out

Your program should behave as follows:

Display a welcome message

Repeatedly do the following:

Ask the user to choose a bet type (or cash out) if number bet or color bet

Ask the user for the number - if number bet Ask the user for color - if color bet

Ask the user to choose an amount to bet (between 1 chip and the total number of chips the user currently has), and record the bet amount

Spin the wheel and report the number and color

Inform the use of their win/loss status, and updated the users chip total appropriately

Until the user chooses to cash out or has no more chips left to bet

Once the user chooses to cash out a final report is displayed indicating the users winnings or loses (relative to their starting with 100 chips).

Rules and Requirements:

All user input must be validated

Given the following method heading, you must write the corresponding definition for a void return

method that displays a welcome message containing the bet types and payouts to the screen.

 public static void welcome() 

Given the following method heading, you must write the corresponding definition for a int return method that displays a menu and reads, validates, and returns the users choice to place a specific bet type or cash out.

 public static int getMenuChoice(Scanner stdIn) 

Given the following method heading, you must write the corresponding definition for a int return

method that reads, validates, and returns a number to bet on, which must be between 0 and 36.

 public static int getNumber(Scanner stdIn) 

Given the following method heading, you must write the corresponding definition for a String return

method that reads, validates, and returns a color to bet on, which must be "Red" or "Black".

 public static String getColor(Scanner stdIn) 

Given the following method heading, you must write the corresponding definition for a int return method that takes the number of chips the user currently has: chipsNow as its only input. Then reads, validates, and returns a bet amount, which must be between 1 and chipsNow.

 public static int getBet(Scanner stdIn, int chipsNow) 

Given the following method heading, you must write the corresponding definition for a String return method that takes the number just spun on the wheel : spinNum as its only input. Then determines and returns the spin color based on spinNum. i.e. "Red", "Black", or "Green"

 public static String determineColor(int spinNum) 

Given the following method heading, you must write the corresponding definition for a void return method that takes the number of chips the user currently has: chipsNow as its only input. Then displays the users winnings or loses (relative to their starting with 100 chips) to the screen.

 public static void report(int chipsNow) 

Notes and Tips:

Assuming number is an int variable, the following expression will evaluate to true if number is even: (number % 2 == 0)

No input validation should take place in the main method.

Try a bottom-up approach, in which you first implement all of the non-main methods, and then

provide an implementation for the main method.

It may be helpful to implement a single wheel spin first, and then allow the user to play multiple spins next.

Sample Runs:

############################ # WELCOME TO ROULETTE # ############################ # NUMBER BETS PAYOUT: 35:1 # # COLOR BETS PAYOUT: 1:1 # ############################ 

You have 100 chips 

1. Pick a number to bet on 2. Pick a color to bet on 3. Cash out 

Enter a choice [1-3]: 0 Enter a choice [1-3]: 4 Enter a choice [1-3]: 1 

Enter the number to bet on [0-36]: -1 Enter the number to bet on [0-36]: 37 Enter the number to bet on [0-36]: 0 

Enter the number of chips to bet [1-100]: 0 Enter the number of chips to bet [1-100]: 101 Enter the number of chips to bet [1-100]: 5 

Spinng the wheel ... Spin number: 31 Spin color : Black 

Sorry, you lost You now have 95 chips 

1. Pick a number to bet on 2. Pick a color to bet on 3. Cash out 

Enter a choice [1-3]: 2 

Enter the color to bet on [Red or Black]: umm Enter the color to bet on [Red or Black]: red 

Enter the number of chips to bet [1-95]: 50 

Spinng the wheel ... Spin number: 16 Spin color: Red 

Congrats, you won! You now have 145 chips 

1. Pick a number to bet on 2. Pick a color to bet on 3. Cash out 

Enter a choice [1-3]: 3 Thanks for playing, you won a total of 45 chips
