Question: 1 / 510

What do interfaces and abstract classes provide?

A way to define static methods only

A mechanism to separate interface from implementation

Interfaces and abstract classes both provide a mechanism to separate interface from implementation. This is useful in situations where we want to define a set of methods that need to be implemented by a class, but we don't want to specify how those methods should be implemented. This allows for more flexibility and modularity in our code.

Option A is incorrect because interfaces and abstract classes allow for both static and non-static methods to be defined.

Option C is incorrect because interfaces and abstract classes can actually be used to encourage inheritance, as they can define a common set of methods for classes to implement.

Option D is incorrect because interfaces and abstract classes do not relate to casting in any way.
