Java 22 introduces stream gatherers, a new feature for manipulating data streams, implemented through JEP 461. Stream gatherers enable custom intermediate operations, simplifying complex stream manipulations. They include methods like windowFixed, windowSliding, fold, scan, and mapConcurrent, each serving unique purposes. Though still in preview, this addition enhances and customizes Java's Stream API functionality.
