JavaFX provides several layout containers that are used to arrange and organize UI components. Layouts are used to define the position and size of nodes within a scene graph. Here are some of the common layout containers in JavaFX:

1. FlowPane: A flow pane lays out its children in a row, wrapping them to the next row if there is not enough space. It can align the children either horizontally or vertically.

2. HBox and VBox: HBox and VBox are two of the most commonly used layout containers in JavaFX. HBox lays out its children in a horizontal row, while VBox lays out its children in a vertical column.

3. GridPane: A GridPane is used to arrange UI components in a grid of rows and columns. It allows developers to specify constraints for each cell, such as its minimum and maximum size.

4. BorderPane: A BorderPane divides the scene into five regions: top, bottom, left, right, and center. Each region can contain a single UI component, and the center region will expand to fill any remaining space.

5. StackPane: A StackPane is used to stack UI components on top of one another. The most recently added child will be at the top of the stack and will be displayed in front of the other children.

6. AnchorPane: An AnchorPane is used to anchor UI components to the edges of the parent container. You can specify the distance between the component and each edge of the container.

7. TilePane: A TilePane lays out its children in a grid, but unlike a GridPane, it does not allow you to specify constraints for individual cells. Instead, it simply divides the space equally among its children.

These are just a few of the layout containers provided by JavaFX. Choosing the right layout container for your application will depend on your specific requirements and the design of your UI.
