Answer the following statements true (T) or false (F)

Question

1. In the RGBA color system, every color is represented by its red, green and blue color values, each ranging from 0 to 255, where 0 denotes no color and 255 full color. The alpha value (A)—which ranges from 0.0 to 1.0—represents a color’s opacity, with 0.0 being completely transparent and 1.0 completely opaque.
2. To respond to ListView selection changes, you register a listener for the SingleSelec- tionModel’s selectedItem property.
3. To create a custom ListView cell format, you must first define a subclass of the Cell- Format generic class (package javafx.scene.control) that specifies how to create a ListView cell.
4. You can build JavaFX GUIs only by using Scene Builder.
5. JavaFX’s TableView control (package javafx.scene.control) displays tabular data in
rows and columns, and supports user interactions with that data.
