In Java, an interface is a reference type used to define a contract that classes can implement. It consists of method declarations (without implementations), and any class that implements the interface must provide concrete implementations for those methods. Interfaces are used to achieve abstraction and multiple inheritance in Java.

Interfaces are used for:

  1. Abstraction – They hide implementation details and show only method signatures.

  2. Polymorphism – Objects can be accessed through interface types, enabling flexible and interchangeable code.

  3. Multiple inheritance – A class can implement multiple interfaces, overcoming Java’s restriction of single inheritance with classes.

Java 8 and later versions also allow default and static methods in interfaces, providing basic implementations:

Interfaces are fundamental in Java frameworks (like Spring) and APIs to ensure loose coupling and scalability in application design. They help in defining clear contracts and promoting reusable, maintainable code
