Any functional interface that you have used from Spring? 🤔

Q1.I have used Predicate , Consumer , Function functional interfaces. Q2. Yes, we can have static and default methods in the functional interface. But only one abstract method. Q3.why functional interface ignores Object class method ? If a Class implements the interface having same method signature as in Object class , then by default every class extends Object class and it leads to conflict between the same methods defined in the object class and in the interface Please correct me if I'm wrong.

Runnable interface, Consumer interface, Supplier interface is used in Functional interface but serializable interface , cloneable interface is used in Marker interface

Please explain why "@overridden" methods are ignored

@9429963654 6 ай бұрын

They are not actually "ignored" If an interface is a functional interface, then it means it would have one method, which is abstract and the implementation of that abstract method needs to defined by any class implementing the interface or any lambda. When your interface has any method which is present in Object class, because all the class are derived from Object class, when you create an implementation of that interface, you would not need to define any implementation of that method -- the implementation is already present in the parent Object class.

The methods present in object class cannot be used in any functional interface, because they are already present in each class by default.... if you wish to use them then the only solution is providing a new implementation that is by changing the name of the method or by adding some arguments (method overloading).

Perfect !

Equals method will be ignored that's why it's not be candidate for functional interface

Here i wanted to ask you one question regarding functional interface. Can functional interface implement any other functional interface or normal interface?
