Can you call super in an overridden method?
You want to still execute the parent method, but then do also do something else. But, since you have overridden the parent method how can you still call it? You can use super.
How do you identify if a method is an overridden method?
Reflection can be used to determine if a method is overridden. The code is a little bit tricky. For instance, you need to be aware that you have a runtime class that is a subclass of the class that overrides the method. You are going to see the same runtime classes over and over again.
What if the overridden method of the superclass has to be called?
The ability of a subclass to override a method allows a class to inherit from a superclass whose behavior is “close enough” and then to modify behavior as needed. An overriding method can also return a subtype of the type returned by the overridden method. This subtype is called a covariant return type.
When an overridden method is called?
Declaring a method in sub class which is already present in parent class is known as method overriding. In this case the method in parent class is called overridden method and the method in child class is called overriding method.
Can a super method be called inside an overridden method?
If you follow the call stack, you can see that this never changes, it’s always the instance created in main (). You can only access overridden methods in the overriding methods (or in other methods of the overriding class). So: either don’t override method2 () or call super.method2 () inside the overridden version.
What happens when you call Super in overriding?
A call to super will perform any logic the class you’re extending has defined for that method. Take into account that it might be important the moment when you call super ‘s implementation in your method overriding. For instance: A call to B.save () will perform the save () logic for both A and B, in this particular order.
How is calling a super method handled in Java?
Every method call is handled individually, so even if you got to SuperClass.method1 () by calling super, that doesn’t influence any other method call that you might make in the future.
When to call parent overridden method in Java?
When you override the display () method in the child, calling it from child object will call the overridden method instead of the parent’s because it’s overridden. If you want to perform some operation and at the same time call the parent’s method as well then you need to call super.display () to execute the parent’s display () method.
