Example Usage

The Gatherers4j class is the main entrypoint for this library.

Here’s a simple example that imports Gatherers4j, sets up a Stream<String>, keeps the last three elements, and puts them in a List<String>:

import com.ginsberg.gatherers4j.Gatherers4j;
import java.util.stream.Stream;

Stream.of("A", "B", "C", "D", "E")
    .gather(Gatherers4j.takeLast(3))
    .toList();

// Returns: [ "C", "D", "E" ]
