Introduction

A Stream represents a sequence of elements and supports different kind of operations to perform computations upon those elements. With Java 8, Collection interface has two methods to generate a Stream: stream() and parallelStream(). Stream operations are either intermediate or terminal. Intermediate operations return a Stream so multiple intermediate operations can be chained before the Stream is closed. Terminal operations are either void or return a non-stream result.

Syntax

• collection.stream()
• Arrays.stream(array)
• Stream.iterate(firstValue, currentValue -> nextValue)
• Stream.generate(() -> value)
• Stream.of(elementOfT[, elementOfT, …])
• Stream.empty()
• StreamSupport.stream( iterable.spliterator(), false )
