Introduction
Explore the fundamentals of Java 8 Stream API, including stream creation from collections and arrays, and the difference between intermediate and terminal operations. Learn how streams enable efficient and flexible data transformations without modifying original sources.
We'll cover the following...
The addition of the Stream API was one of the major features added to Java 8. A Stream in Java can be defined as a sequence of elements from a source that supports aggregate operations on them. The source here refers to collections or arrays that provide data to a stream.
