Answer
Interfaces define a set of methods that implementing classes must fulfill.
In Java, interfaces act as contracts that specify what methods a class must implement. This ensures consistency across different classes that share common behavior. For example, if you have an interface `Payable` for processing payments, any class implementing `Payable` must provide an implementation for all its methods, such as `processPayment()`.
