Can an interface inherit another interface in programming?
Yes, in many programming languages, an interface can inherit from another interface. This allows for a more structured and reusable design.
Can you give me an example of this in Java?
Sure! In Java, you can have an interface Animal
and another interface Pet
that extends Animal
. This means Pet
inherits the methods of Animal
.
What happens if the child interface adds new methods?
If the child interface adds new methods, any class that implements the child interface must provide implementations for both the inherited and the new methods.
Are there any limitations to interface inheritance?
Yes, an interface can extend multiple interfaces, but it cannot inherit from classes. Also, all methods in an interface are abstract by default.
