Answer
Use InterfaceName.super.methodName(). Frame the concept in practical terms so you can explain it during interview discussion.
A class can call a default method from an interface using 'InterfaceName.super.methodName()'. This is useful when the class overrides the default method but still wants to use the interface's version. For instance, in 'class Payment', calling 'PaymentGateway.super.processPayment()' allows access to the interface's default implementation.
