In Java, an interface is a blueprint for a class, defining a set of methods that a class implementing the interface must provide. It specifies what methods a class should have without specifying how they should be implemented. Interfaces allow for multiple inheritance-like behavior by enabling a class to implement multiple interfaces, facilitating the creation of loosely coupled, interchangeable components. They promote code reusability, modularity, and help define contracts between different parts of a program or between libraries, enabling polymorphism and abstraction in Java programming. read less
