streamflatMap
StreamflatMap is a programming concept found in many modern programming languages, particularly those supporting functional programming paradigms like Java 8 and beyond. It is a method on streams that allows for transforming each element of a stream into zero, one, or multiple other elements, and then flattening these resulting streams into a single new stream. This is in contrast to a simple map operation, which transforms each element into exactly one other element.
The flatMap operation is particularly useful when dealing with nested data structures or when an operation
Essentially, flatMap combines the functionality of a map operation followed by a flattening operation. It takes
