A Mono<T> is a Publisher that emits 0 or 1 element. Use Mono.just() to wrap a value and .subscribe() to consume it.

Create a Mono that emits the string "Hello Reactor" and subscribe to it, printing the value.

A Mono<T> is a Publisher that emits 0 or 1 element. Use Mono.just() to wrap a value and .subscribe() to consume it.

Why this works

Mono.just() creates a Mono that emits a single value. The subscribe() method triggers the reactive pipeline and the consumer lambda receives each emitted item.

Expected output

Hello Reactor
