Answer / Rahul Rao
Closures are anonymous functions that can access variables from the enclosing scope, making them useful for creating callbacks. Listeners in Groovy are interfaces with a single method (usually named after an event), allowing classes to subscribe to events and respond accordingly. Closures can be used as listeners by implementing the interface and defining the closure within the method.
