Apr 9, 2025 · Stream was introduced in Java 8, the Stream API is used to process collections of objects. A stream in Java is a sequence of objects that supports various methods that can be pipelined to produce the desired result.

Streams are lazy; computation on the source data is only performed when the terminal operation is initiated, and source elements are consumed only as needed. Collections and streams, while bearing some superficial similarities, have different goals.
