Java 16 introduced mapMulti(), a Stream API method offering flexible element transformation. Unlike map() and flatMap(), mapMulti() allows mapping a single element to multiple or zero elements using a BiConsumer. This provides more control over complex transformations, particularly useful when the output size isn't predictable. mapMulti() takes a BiConsumer, where the first argument is the input element and the second is a Consumer to add elements to the output stream. This enhances readability and conciseness for intricate data manipulation within streams.
