Replacing numbers

My problem here is that I am trying to get the getBigJackpot() to correctly woork. If I were to win say 10 coins, it would store in an int, but if I were to win 5 coins, that 10 would stay and disregard the 5 coins won. If I were to win 15 coins, it would replace the 10. I don't know which way to go with this.

Line 153 is where this starts.

int i = 0; return i;

this will always return 0, and you are not actually setting a value that is used outside of that get method. a getter also isn't the right way to set values. what exactly is it that you are trying to do? which value should be changed? when? into what value?

well i guess you'd have a global variable say coins... And the method would consist of if else statements that compare the new amount of coins against the old amount. The new amount of coins could be passed to the method via arguments and your total highest coins won so far would be stored in the global variable. your if statment might go like:

private static coins=0;
..
method(double newAmountWon) {
if(coins<newAmountWon) {//the new amount won was greater
coins=newAmountWon;//set the global total of our highest bet to a new higer bet
} else {
//do nothing because the amount won wasnt higher then the old amount 
}
}

I can see I also missed an important part for this issue as well...

I have created a getter and a setter to hopefully grab the big jackpot and save it for reference later but inside I am drawing another blank as to how to return the big bet from inside a static method on a non static int variable.
