AbstractApplicationContext vs ApplicationContext

Question

what is the difference between AbstractApplicationContext and ApplicationContext ? can we call

context.registerShutdownHook()  
         


        

Answer 1

Same as the diff between abstract class (AbstractApplicationContext ) and an interface (ApplicationContext).

Can we call context.registerShutdownHook() using ApplicationContext?

No, because registerShutdownHook() is part of ConfigurableApplicationContext interface which is not extended by ApplicationContext
