Explain why closures and listeners are used in groovy.
Answer / Satya Nand Mishra
Closures and listeners are fundamental features of Groovy that help to simplify and improve the development process. Closures are anonymous functions that can be defined within other functions, making them ideal for creating callbacks or handling asynchronous events.nListeners are interfaces in Java that provide a way for classes to be notified when certain events occur within another class. In Groovy, this concept is simplified with the use of closures as event handlers.
