Answer
They define methods for dynamic method resolution.
Interfaces in Java allow different classes to be treated through a common type, promoting polymorphism. They define a contract that implementing classes must fulfill. For example, if both `Dog` and `Cat` implement `Pet`, they can be treated as `Pet` types, allowing method calls like `makeSound()` without knowing the specific class.
