title: Check which Button object is clicked using JavaFX
body: <p>I am making a basic calculator but I am unsure of how to check if a certain <code>Button</code> has been clicked. I want to use an array of Button objects and then check to see if the button clicked matches a button object in the array. My code for this is below.</p>
  
  <pre><code>Button[] digitButtons = { bt0, bt1, bt2, bt3, bt4, bt5, bt6, bt7, bt8, bt9 };
  
  for (int index = 0; index &lt; 9; index++) {
      int position = -1;
      if (buttonClicked == digitButtons[index]) {
          position = index;
          break;
      }
  }
  </code></pre>
