Jun 4, 2024 · A Stream is a sequence of components that can be processed sequentially. These packages include classes, interfaces, and enum to allow functional-style operations on the elements. The stream can be used by importing java.util.stream package. Stream API is used to process collections of objects.
Java Streams API, introduced in Java 8, provides a very efficient and expressive way to handle streams of data, including files. In this context, the term "streams" refers to a sequence of elements supporting sequential and parallel aggregate operations, not to be confused with InputStream and OutputStream from I/O streams.
