Roulette Program

[CircuitConcepts]

I've been working on this program for a spot of fun lately. I'm not a super experienced coder with Java, but don't worry about dumbing things down. This program isn't very complex in itself, but for some reason it isn't doing what I want it to!

import java.io.*;
import java.util.Random;
import java.text.DecimalFormat;

public class Roulette
{
	public static void main (String args[]) throws IOException
	{
		BufferedReader input = new BufferedReader (new InputStreamReader (System.in));
		Random generator = new Random();
		DecimalFormat dollarOutput = new DecimalFormat ("$00.00");
		
		char userInput;
		char userInput2;
		char betType;
		char spinSuccess;
		char successType;
		char eOSuccessType;
		int betNum;
		int rouletteSpinNum;
		int quadrant;
		double userMoney = 100.0;
		double betAmount;
		
		System.out.println("Welcome to Thomas' Casino of Luck!");
		System.out.println("How about spin of Roulette?");
		
		do{
			System.out.print("\nType in 'y' to play, 'n' to quit or 'r' for the rules.\t");		
			userInput = (input.readLine()).charAt(0);
			
			if (userInput == 'y')
				{
					System.out.println("\nYou have\t\t\t\t" + dollarOutput.format(userMoney) + ".");
					System.out.print("How much do you want to bet?\t\t");
					betAmount = Double.parseDouble(input.readLine());

						{
							System.out.println("You can't bet what you don't have!");
						}
					else{					
						System.out.print("\nWould you like to bet on:\n\t'e' evens\n\t'o' odds\n\t'q' a quadrant\n\t's' for a specific number\t");

	}
}

It's a simple game of roulette, though be warned as its under construction, quadrants don't function. Only snippets of the code for it are there.

Here's my problem: If you opt to bet on evens or odds you always win. Even if it rolls a 97 it will happily tell you, you got a 97 and bet on evens and then give you your money back!

I've become clueless, staring at the code so much gets to meh.

Thanks!
