Java Streams Tutorial | 2020

Java Streams allows you work with Collections/Lists like never before. In the good old days we use to define every single step (code) what we wanted to accomplish, we used to write a lot of code for something very small (The Imperative approach).

What Java Streams makes it easy to work with Collections and it gives you as a developer an API where you can ask what you want instead of defining the full implementation for the thing you want. (Declarative Programming)

If you not using Java Streams ???? then you should take a moment and watch this video to learn more about it.

The first thing visible in Java 8 is the lambdas, but the real power is in Streams. If you're interested in immersing into lambdas and streams, this is the session for you. We will start with lambda expressions, learn about how to use them and how they get implemented under the hood. Then we will swiftly move into learning about streams, the abstractions they provide, and a variety of operations we can do with them. We will conclude with a discussion about lazy evaluations, infinite streams, and parallel collections.

17.11 Stream API in Java 8 Tutorial

Classes to support functional-style operations on streams of elements, such as map-reduce transformations on collections.

Stream operations are divided into intermediate and terminal operations, and are combined to form stream pipelines.

I Have a Java 8 Stream

The new lambda language features in Java SE 8 are catalysts for new APIs that would previously have been impractical or impossible. The Streams API, which enables bulk operations on collections and other aggregates, sequentially or in parallel, is one such example that is the centerpiece of the Java SE 8 libraries. This session, primarily via the IDE and Java tooling, examines the Stream API, architecture, and implementation in detail so that developers can learn how to use the API, get good performance and scalability, and apply the same design techniques to their own APIs.

Programming with Streams in Java 8 | Venkat Subramaniam

We all have heard about lambda expressions in Java 8, but the real unsung heroes of Java 8 are the streams. This presentation takes an example-driven approach to explore streams, their core capabilities from the application development point of view, and how to explore these capabilities to improve performance and efficiency.

Overview of Java 8 Parallel Streams (Part 1)

This video gives an overview of Java 8 parallel streams, giving an intro on how aggregate operations in a parallel stream work.

Java Streams: Beyond The Basics

(Recorded at Jfokus 2016.

Java Streams: Beyond The Basics

Lambda expressions and the streams API add a more functional style of programming to Java; something developers have not really had in the past. The session will start with a short summary of the key features of both Lambda expressions and streams before moving on to some real world examples of how to use them effectively, including some pitfalls that should be avoided. We'll finish off with a quick look at some of the ideas for improvements to streams in JDK 9.

JDK 8: Lessons Learnt With Lambdas and Streams

Recorded at SpringOne Platform 2016.
Speaker: Simon Ritter, Azul
Slides:

Lambda expressions and the streams API add a more functional style of programming to Java; something developers have not really had in the past.

This session will start with a short summary of the key features of both Lambda expressions and streams before moving on to some real world examples of how to use them effectively, including a number of lessons learnt from trying to apply an imperative style of programming when it should have been functional.

We'll finish off with a quick look at some of the ideas for improvements to streams in JDK 9.
