Thread: Help with array nots being updated

Two spots in my code not working as enteneded if anyone could help tell me were im going wrong would be grateful in one spot it seems to be skipping threw my if statement and the other is not updating on my counter at the end

sample output :
Enter Wheel Size/odds
2
Do you want to play?
Type: b to bet
Type q to quit
b
How much do you want to bet?(1-500)
12
You bet 12$
What number do you want to bet on ?1-2
1
You bet on 1
Do you want to bet on another number?
If yes type: a
To spin type: s
// this is were i need the help when you hit a do you need to throw each extra bet into an array or can you use some type of if statement?

To spin type: s
s
You got1
Congratz you Won 12
You now have 512$
You chose to quit
Do you want to play?
Type: b to bet
Type q to quit
q
Wins: 1Losses : 0
// this is were i need the counter to say 2 came up 3times or however many times your spinned till u quit
Net gains :12

a
If you bet a number leave a space between each number
You got12
Congratz you Won 132
Sorry you lost 12
You now have 488$
Type: b to bet
Type q to quit


it works without throwing an error just seem to be skipping it when i hit a to go into the if statement i get the print statement then it gives be both a win and loss statement for some reason not really sure were the error is

--- Update ---

purpose of the data being saved is that each extra bet need to be compared to the final spin

it seems to be splitting the string and placing in array but after that it errors
String.charAt(int) line: not available
Roulette.main(String[]) line: 41

instead of going down the line after the if statement is parsed it kicks it out to the begining do statement

java.lang.StringIndexOutOfBoundsException: String index out of range: 0
this is all im getting as an error

i tried that thats not the issue just makes my hit "a" twice then acts like i hit my spin option anyway

i dont believe my scans are the issue im using different scanners for each type so i dont run into that issue its why i have scan1, scan2,scan3
