fromArray

As explained in Spring in Action, Sixth Edition

fromArray is a Project Reactor factory operation that creates a Flux from an array's elements.

fromArray is a Project Reactor factory operation that creates a Flux from the elements of an array. The resulting Flux emits the array values in order and then completes. section 11.3.1

Create and verify a fruit Flux

Declare a String array, pass it to Flux.fromArray(), and use StepVerifier to check each emitted fruit and verify completion. section 11.3.1

How Spring in Action, Sixth Edition covers it

How deep it goes
Shows the static call and a complete verification test, but does not explain implementation internals.
Examples
Uses a five-element fruit array containing Apple, Orange, Grape, Banana, and Strawberry.
What it assumes
Assumes familiarity with Java arrays and introduces the reactive Flux creation pattern through a concrete test.
What you can do after
Apply it via Project Reactor and verify ordered emissions and completion with StepVerifier.
How it connects
Connects Flux creation with StepVerifier, fromIterable(), and fromStream().
