I am trying to make a roulette game but I don't know what to do here as I have made the code but it is not working and not organized. For example, when the user clicks on spin button a random number gets generated and put onto the textarea where if it even it will go on the even column, odd than odd column, zero than zero columm

the best represention of the area would be this:

Odd Even Zero

$9$

$2$

$23$

$0$

this is my code now:

import java.awt.event.ActionEvent;
