title: Cannot resolve method getChildren.addAll();
body: <p>Okay, I am not sure if I am asking this in the right place but I am hoping someone here can help me. So, I am a beginner at Java and I am trying to make a JavaFX application but my Layout 1 "getChildren.addAll(label1, button1);" is being labeled as an error. That error is:</p>
  
  <p>Cannot resolve method 'addAll(java.awt.Label, javafx.scene.control.Button)'</p>
  
  <p>Any advice or help toward the problem is greatly appreciated. Thank You, if you read this.</p>
