Javafx button sending arguments to ActionEvent function
<p>I'm learning how to use javafx, along with scenebuilder by creating a very basic calculator but I've come across a problem where it's hard for me to find a way to not have a seperate function for each button. I need to know if there's a way for a button to change a variable or give arguments to the action event method that the button is linked to so I don't need seperate methods for each button to call another function. This is an example of what I'm working with.</p>

<pre><code>@FXML
private Button one;
private Button two;
//both buttons are linked to NumChange

private void NumChange(ActionEvent e) {
    //update the number to preform an operation with here
}
</code></pre>

<p>How do I have all the number buttons use the same function but send it arguments so it can do different things?</p>

<p>All of the answers I've found involve using getting the text of the button, however my calculator is weird and I'm having the spelled out word on them so I can't do that, what can I do?</p>
