Inspired by the implementation of promise in jQuery, few Java Engineers have started to develop a library called JDeferred. This implements the concept of promise as robustly as it should be by leaving the gaping holes of the java.util.concurrent package. This was a brief of how JDeferred works. Let's dive deep into what it is and its unique advantages, as compared to other implantations available in the market.

Just like jQuery has a deferred object, JDeferred is designed in a similar way to behave and contact with Java's compiler. JDeferred is not only similar with jQuery's implementation of promise, but it also extends its support to the Android Deferred Object. Chapter 8, Promises in jQuery is the dedicated chapter on jQuery and its mechanism and working on promise, so we can skip that part for now and see what the Android Deferred Object is, and how it fits into the implementation of promise.
