Implementing Java Interfaces

Clojure runs on the Java Virtual Machine (JVM), which means it can interact with Java code. This powerful feature is called Java Interop.

Many Java libraries and APIs expect you to provide objects that implement specific Java interfaces. This lesson teaches you how Clojure helps you meet these expectations seamlessly.

A Java interface is like a contract or a blueprint for a class. It defines a set of methods that a class *must* implement if it claims to adhere to that interface.

• Interfaces declare method signatures (name, arguments, return type) but provide no implementation.
• They enable polymorphism, allowing different classes to be treated uniformly if they implement the same interface.
• Essential for callback mechanisms and API extensibility in Java.
