title: Javafx button sending arguments to ActionEvent function
body: <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>
