Introduction of Java 8 with emphasis on Lambda Expressions and StreamsEmiel Paasschens
Lambda expressions and streams are major new features in Java 8. Lambda expressions allow treating functionality as a method argument or variable. Streams provide a new way to process collections of objects in a declarative way using intermediate and terminal operations. The document provides examples of lambda expressions, method references, functional interfaces, default methods on interfaces, and stream operations like filter, map, and reduce.
The document is a presentation on lambda expressions in Java 8 given by Isaac Carter. It introduces lambda expressions and functional programming concepts in Java 8 such as functional interfaces, streams, and method references. It provides examples of using lambda expressions with common Java 8 APIs like forEach(), Predicate, and stream(). The presentation emphasizes thinking declaratively rather than imperatively in Java 8 and leveraging lambda expressions to let Java do more of the work.
Lambda expressions allow implementing functional interfaces using anonymous functions. Method references provide a shorthand syntax for referring to existing methods as lambda expressions. The Stream API allows functional-style operations on streams of values, including intermediate and terminal operations. The new Date/Time API provides a safer and more comprehensive replacement for the previous date/time classes in Java.
Java is Object Oriented Programming. Java 8 is the latest version of the Java which is used by many companies for the development in many areas. Mobile, Web, Standalone applications.
Java 8 is coming soon. In this presentation I have outlined the major Java 8 features. You get information about interface improvements, functional interfaces, method references, lambdas, java.util.function, java.util.stream
Java 8 will include many new features including lambdas, default methods on interfaces, and a date/time API. Lambdas allow implementing functional interfaces with expression syntax rather than anonymous classes, and method references allow referring to methods without invoking them. Default methods allow adding new functionality to interfaces without breaking existing implementations. The new date/time API in JSR-310 provides improved date/time handling functionality.
The document outlines Java 8's Stream API. It discusses stream building blocks like default methods, functional interfaces, lambda expressions, and method references. It describes characteristics of streams like laziness and parallelization.

It provides examples of common stream API methods like forEach, map, filter, findFirst, toArray, collect, and reduce.
The Dark Side Of Lambda Expressions in Java 8Takipi
This document discusses the "dark side" of Lambda expressions in Java 8. It notes that while Lambda expressions allow for more concise code, they can make debugging more difficult since the bytecode generated no longer closely matches the source code written. This is due to the JVM remaining oblivious to Lambda expressions. The distance between source code and bytecode is even greater for languages like Scala, JavaScript, and Nashorn, leading to longer, harder to understand call stacks when exceptions occur.

Actors are a model of concurrent computation that treats isolated "actors" as the basic unit. Actors communicate asynchronously by message passing and avoid shared state. This model addresses issues in Java's thread/lock model like deadlocks. In Gpars, actors include stateless actors like DynamicDispatchActor and stateful actors like DefaultActor. The demo shows examples of stateless and stateful actors in Gpars.
Scala is a programming language that runs on the JVM and fuses functional and object-oriented paradigms. It aims to provide functional programming for programmers with an imperative mindset. Key features include functions as first-class values, pattern matching, traits for composition, and seamless interoperability with Java. While some features appear to be language features, many are actually implemented via libraries. The Scala community is growing with adoption by companies and increasing support in tools and publications.

Generics are one of the features of Swift that set it apart from many other languages. Since Swift debuted, developers have been wondering when to use them and what to use them for. By looking at the standard library, which is the first piece of software to use generics, we can better understand their purpose and utility.
If you've programmed in Java in the past decade then you know what generic types are. Generics are used everywhere but rarely understood on a deep level. In this talk, Bryan will show not only classic "container" generic classes but also how to build simple, but highly flexible frameworks in all tiers (GUI, Service and DAO tiers).
Java Generics Introduction - Syntax Advantages and PitfallsRakesh Waghela
This document provides an overview of Java generics. It discusses what generics are, their history and motivation, how they improved type safety over non-generic collections. Key points covered include the Collections Framework being rewritten using generics, concepts like type erasure and type parameters.

This document discusses Reactive Streams and RabbitMQ. It covers producer/consumer models like request/response where data is pulled, and asynchronous subscription where data is pushed. It also mentions potential issues like queue overflow, resource exhaustion, and denial of service attacks. Finally, it lists several stream libraries and frameworks including Java and Scala streams, Play Iteratees, RxJava, and Akka Streams that can be used to implement Reactive Streams patterns with RabbitMQ.
^Regular Expressions is one of those tools that every developer should have in their toolbox. You can do your job without regular expressions, but knowing when and how to use them will make you a much more efficient and marketable developer. You'll learn how regular expressions can be used for validating user input, parsing text, and refactoring code. We'll also cover various tools that can be used to help you write and share expressions.$
Regular expressions (RegEx) are patterns used to match character combinations in strings. They were invented in the 1950s and exist in different flavors that may implement patterns differently. RegEx can be used to search, edit, and manipulate strings in programming languages and text editors. Common patterns include characters, character classes, quantifiers, anchors, groupings, lookarounds, and modifiers. Mastering RegEx provides powerful string searching and manipulation capabilities.
Lecture: Regular Expressions and Regular LanguagesMarina Santini
This document provides an introduction to regular expressions and regular languages. It defines the key operations used in regular expressions: union, concatenation, and Kleene star. It explains how regular expressions can be converted into finite state automata and vice versa. Examples of regular expressions are provided. The document also defines regular languages as those languages that can be accepted by a deterministic finite automaton. It introduces the pumping lemma as a way to determine if a language is not regular. Finally, it includes some practical activities for readers to practice converting regular expressions to automata and writing regular expressions.

The Scala community is growing, with industrial adoption starting at companies like Twitter.
Functional Programming With Lambdas and Streams in JDK8IndicThreads
The significant new language feature in Java SE 8 is the introduction of Lambda expressions, a way of defining and using anonymous functions. On its own this provides a great way to simplify situations where we would typically use an inner class today. However, Java SE 8 also introduces a range of new classes in the standard libraries that are designed specifically to take advantage of Lambdas. These are primarily included in two new packages: java.util.stream and java.util.function.
After a brief discussion of the syntax and use of Lambda expressions this session will focus on how to use Streams to greatly simplify the way bulk and aggregate operations are handled in Java. We will look at examples of how a more functional approach can be taken in Java using sources, intermediate operations and terminators. We will also discuss how this can lead to improvements in performance for many operations through the lazy evaluation of Streams and how code can easily be made parallel by changing the way the Stream is created.
Session at the IndicThreads.com Confence held in Pune, India on 27-28 Feb 2015
http://www.indicthreads.com
http://pune15.indicthreads.com
This document provides an overview of Java 8 lambda features such as lambda syntax, interface enhancements like default methods, converting anonymous classes to lambdas, forEach and streams, method and constructor references, and functional interfaces. It also lists several sessions at a conference that will provide more in-depth coverage of these Java 8 lambda topics and includes links to documentation and additional resources.
This document provides a brief overview of Java 8 features including functional interfaces, lambda expressions, stream API, and Optional class. It discusses how functional interfaces provide target types for lambda expressions and can have a single abstract method. Lambda expressions allow implementing functional interfaces concisely without anonymous classes. The stream API provides a powerful way to process collections in a declarative way using lambda expressions. The Optional class avoids null pointer exceptions and allows chaining of method calls on objects that may be null.
Project Lambda: Functional Programming Constructs in Java - Simon Ritter (Ora...jaxLondonConference
Presented at JAX London 2013
The big language features for Java SE 8 are lambda expressions (closures) and default methods (formerly called defender methods or virtual extension methods). Adding lambda expressions to the language opens up a host of new expressive opportunities for applications and libraries. You might assume that lambda expressions are simply a more syntactically compact form of inner classes, but, in fact, the implementation of lambda expressions is substantially different and builds on the invokedynamic feature added in Java SE 7.
Presentation on the new features introduced in JDK 8, presented on the 26.02.2013 in Sofia University in front of students and members of the Bulgarian java user group.
The document discusses Java 8 Streams, which provide a way to process data in a functional style. Streams allow operations like filter, map, and reduce to be performed lazily on collections, arrays, or I/O sources. The key aspects of streams are that they are lazy, support both sequential and parallel processing, and represent a sequence of values rather than storing them. The document provides examples of using intermediate operations like filter and map and terminal operations like forEach and collect. It also discusses spliterators, which drive streams and allow parallelization, and functional interfaces which are used with lambda expressions in streams.

Lambda Chops - Recipes for Simpler, More Expressive CodeIan Robertson
While the new Streams API has been a great showcase for lambda methods, there are many other ways this new language feature can be used to make friendlier APIs and more expressive code. Lambdas can be used for a number of tasks which historically required significant boilerplate, type-unsafe constructs, or both. From new ways to express metedata, to emulating Groovy's null-safe navigation operator, we'll take a look at a myriad of ways, big and small, that you can use lambdas to improve APIs and streamline your code. We'll also look at some of the limitations of lambdas, and some techniques for overcoming them.
Project Lambda: To Multicore and BeyondDmitry Buzdin
This document outlines Project Lambda, which aims to add closures and related features to Java SE 8 to better support programming in a multicore environment. It discusses how hardware trends are leading to parallelism and how developers need simple parallel libraries. It proposes lambda expressions and method references to make parallel programming easier by allowing internal iteration idioms instead of serial for loops. Lambda expressions allow code to be passed as data in a concise way, avoiding boilerplate. Their type is a single-abstract-method (SAM) interface. Method references further simplify code by extracting data dependencies.
This document provides an overview of Java 8 including:
- Java 8 has approximately 9 million developers and Oracle supports versions 6-8.
- New features include default methods, lambda expressions, streams, and parallel processing capabilities.
- JavaScript integration allows JavaScript code to be run from Java, enabling database and other connections from JavaScript.
- Potential issues with Java 8 include more complex debugging due to lambda expressions and increased abstraction.
