Explain the life cycle of a JavaFX Application
85 Lectures 6 hours
The JavaFX Application class has three life cycle methods, which are −
start() − The entry point method where the JavaFX graphics code is to be written.
stop() − An empty method which can be overridden, here you can write the logic to stop the application.
init() − An empty method which can be overridden, but you cannot create a stage or scene in this method.
In addition to these, it provides a static method named launch() to launch JavaFX application.
Since the launch() method is static, you need to call it from a static context (main generally). Whenever a JavaFX application is launched, the following actions will be carried out (in the same order).
An instance of the application class is created.
Init() method is called.
The start() method is called.
The launcher waits for the application to finish and calls the stop() method.
Terminating the JavaFX Application
When the last window of the application is closed, the JavaFX application is terminated implicitly. You can turn this behavior off bypassing the Boolean value “False” to the static method setImplicitExit() (should be called from a static context).
You can terminate a JavaFX application explicitly using the methods Platform.exit() or System.exit(int).
