How to create a StackPane using JavaFX?

Once you create all the required nodes for your application you can arrange them using a layout. Where a layout is a process of calculating the position of objects in the given space. JavaFX provides various layouts in the javafx.scene.layout package.
In this layout, the nodes are arranged as a stack from bottom to top (one upon another). You can create a stack pane in your application by instantiating the javafx.scene.layout.StackPane class.
You can set the alignment of the nodes in this pane using the setAlignment() method.
You can set the alignment of the nodes in this pane using the setAlignment() method.
In the same you can set a margin for a node within the pane, using the setMatgin() method.
In the same you can set a margin for a node within the pane, using the setMatgin() method.
To add nodes to this pane you can either pass them as arguments of the constructor or, add them to the observable list of the pane as −
getChildren().addAll();
