JDeferred is a Java Deferred/Promise library modeled after jQuery's Deferred object, supporting promise callbacks, multiple promise composition (when/race/settle), and generics-typed resolve/reject/notify. It works on the JVM and Android and is Java 8 lambda friendly.

Use cases

• manage async callbacks in java without callback hell
• combine multiple async tasks with when/race/settle
• promise library for android development
• wrap runnable and callable tasks as promises
• report progress of long-running async operations

When to choose

• you want jQuery-style deferred/promise semantics on the JVM or Android
• you need generics-typed promises with progress notifications
• you want to compose multiple async operations

When to avoid

• you're on Java 8+ and can use CompletableFuture instead
• you need reactive streams like RxJava or Project Reactor
• you need a very actively maintained project - latest release is 2021
