Streams in Java

Flashcards for reviewing the concept of streams in Java, including basic stream operations, lambda expressions, and parallel streams.

Streams

A way to iterate through an entire collection of elements in a data structure.

Java Streams

A feature introduced in Java 8 that is specifically used on collections to iterate through data structures.

stream()

The method used to create a stream from a collection.

forEach()

A method to process each element in a stream.

Lambda Expression

A compact way to represent a method in Java, often used with streams.

Functional Interface

An interface with a single abstract method, allowing it to be used with lambda expressions.

Consumer Interface

A functional interface that represents an operation to be performed on a single input argument.

Parallel Stream

Utilizes multiple cores of the CPU to process a stream, potentially improving performance through parallel execution.

Asynchronous Process

A stream that may not process elements in the original order due to multi-threading.

parallelStream()

A stream created by calling the method parallelStream() on a collection.
