Introduction to Reactive Programming in Java

Reactive programming is a programming paradigm that is focused on asynchronous data streams and the propagation of changes through those streams. Reactive programming provides a way to handle events in a more efficient and elegant way by allowing developers to write code that reacts to data as it becomes available, rather than waiting for it to be ready.

In Java, Reactive programming is implemented through the Reactive Streams specification, which provides a common API for reactive programming in Java. The Reactive Streams API is based on four core interfaces: Publisher, Subscriber, Subscription, and Processor. These interfaces define how data streams are published, consumed, and transformed by reactive applications.

One of the key benefits of Reactive programming is its ability to handle large amounts of data in real-time. This makes it an ideal choice for applications that require high throughput and low latency, such as financial trading systems, social media platforms, and real-time analytics.

Java libraries

There are several popular libraries for reactive programming in Java. Here are some of the most widely used ones:
