- Clojure functions implement interfaces from Runnable and Callable.
- Clojure data structures implement the Java Collections API.
In addition to these generic interfaces, you will occasionally need domain-specific interfaces. Often this comes in the form of callback handlers for event-driven APIs such as Swing or some XML parsers. Clojure can easily generate one-off proxies or classes on disk when needed, using a fraction of the lines of code necessary in Java.
