You will use the Casino.java (that is provided) to drive the Roulette class (that you will create).
Here is the code for the Casino.java
import java.util.*;

public class Casino {

    public static void main (String[] args) {
       
        Scanner console = new Scanner (System.in);
       
        double wallet = 100.00; //Start the user off with $100
        double bet = 0.00; //User bet
        double result = 0.00; //To store the winnings/losses of each game
        String input = ""; //User input

        //Create instance of the Roulette game (that you're creating)
        Roulette game = new Roulette();
       
        do {
       
            System.out.println("How much would you like to bet?");
            bet = console.nextDouble();
            wallet = wallet - bet;
           
            //Play a round and store the results
            result = game.betOnce(bet);
           
            //Flush the buffer
            console.nextLine();
           
            //Update wallet amount and notify user
            wallet = wallet + result;
            System.out.println("You have $" + wallet + " in your wallet.");
            System.out.println("Bet again? Y or N?");
            input = console.nextLine();
       
        } while (!input.equalsIgnoreCase("N"));
   
    } //end main

} //end class

Your job is to create the Roulette class to interact with the Casino class to allow the user to play the game of Roulette.

Here are the rules:

    Create a class named Roulette with a method named betOnce that takes, as parameters, the amount of the user bet.
    Generate a random number between 0 and 36 (that simulates the wheel - must use Math.random and set the range so it will only return the roulette numbers 0-36)
    The user should be prompted to place their bet on 1) Low or 2) High or 3) a Number
    Use the swtich statement .

    If the user selected 3) a Number, prompt the user to enter a guess between 1 and 36.

    If the user selected
