Java 8 features

Java 8 Features Oracle released a new version of Java as Java 8 in March 18, 2014. It was a revolutionary release of the Java for software development platform. It includes various upgrades to the Java programming, JVM, Tools and libraries. Java 8 Programming Language Enhancements Java 8 provides following features for Java Programming: • Lambda expressions, • Method references, • Functional interfaces, • Stream API, • Default methods, • Base64 Encode Decode, • Static methods in interface, • Optional class, • Collectors class, • ForEach() method, • Nashorn JavaScript Engine, • Parallel Array Sorting, • Type and Repating Annotations, • IO Enhancements, • Concurrency Enhancements, • JDBC Enhancements etc. Lambda Expressions Lambda expression helps us to write our code in functional style. It provides a clear and concise way to implement SAM interface(Single Abstract Method) by using an expression. It is very useful in collection library in which it helps to iterate, filter and extract data. For more information and examples: Method References Java 8 Method reference is used to refer method of functional interface . It is compact and easy form of lambda expression. Each time when you are using lambda expression to just referring a method, you can replace your lambda expression with method reference. For more information and examples: Functional Interface An Interface that contains only one abstract method is known as functional interface. It can have any number of default and...

We’re sorry. We could not find a match for your search. We suggest you try the following to help find what you’re looking for: • Check the spelling of your keyword search. • Use synonyms for the keyword you typed, for example, try "application" instead of "software." • Start a new search. Clear Search • Lambda Expressions, a new language feature, has been introduced in this release. They enable you to treat functionality as a method argument, or code as data. Lambda expressions let you express instances of single-method interfaces (referred to as functional interfaces) more compactly. • Method references provide easy-to-read lambda expressions for methods that already have a name. • Default methods enable new functionality to be added to the interfaces of libraries and ensure binary compatibility with code written for older versions of those interfaces. • Repeating Annotations provide the ability to apply the same annotation type more than once to the same declaration or type use. • Type Annotations provide the ability to apply an annotation anywhere a type is used, not just on a declaration. Used with a pluggable type system, this feature enables improved type checking of your code. • Improved type inference. • Method parameter reflection. • Classes in the new java.util.stream package provide a Stream API to support functional-style operations on streams of elements. The Stream API is integrated into the Collections API, which enables bulk operations on collections, such ...

A lot has changed in Java from its beginnings in 1995 until today. Java 8 was a revolutionary release that put Java back on the pedestal of the best programming languages. We will go through most of the changes in the Java language that happened from Java 8 in 2014 until today. We will try to be as brief as possible on every feature. The intention is to have a reference for all features between Java 8 and Java 17 inclusively. Example Code This article is accompanied by a working code example Java 8 The main changes of the Java 8 release were these: • • • • • • Lambda Expressions and Stream API Java was always known for having a lot of boilerplate code. With the release of Java 8, this statement became a little less valid. The stream API and lambda expressions are the new features that move us closer to functional programming. In our examples, we will see how we use lambdas and streams in the different scenarios. The World Before Lambda Expressions We own a car dealership business. To discard all the paperwork, we want to create a piece of software that finds all currently available cars that have run less than 50,000 km. Let us take a look at how we would implement a function for something like this in a naive way: public class LambdaExpressions To implement this, we are creating a static function that accepts a List of cars. It should return a filtered list according to a specified condition. Using a Stream and a Lambda Expression We have the same problem as in the Our c...

JDK 8 is a superset of JRE 8, and contains everything that is in JRE 8, plus tools such as the compilers and debuggers necessary for developing applets and applications. JRE 8 provides the libraries, the Java Virtual Machine (JVM), and other components to run applets and applications written in the Java programming language. Note that the JRE includes components not required by the Java SE specification, including both standard and non-standard Java components. The following conceptual diagram illustrates the components of Oracle's Java SE products: Java Language Tools & Tool APIs Deployment User Interface Toolkits API Integration Libraries Profiles Other Base Libraries lang and util Base Libraries Java Virtual Machine

Java 8 is a revolutionary release of the world’s #1 development platform. It includes a huge upgrade to the Java programming model and a coordinated evolution of the JVM, Java language, and libraries. Java 8 includes features for productivity, ease of use, improved polyglot programming, security and improved performance. Welcome to the latest iteration of the largest, open, standards-based, community-driven platform. Java ME 8 is now Generally Available-Java ME 8 is an ideal platform for intelligent devices and an optimal foundation for developers to build new services for the IoT. • • Get familiar with lambdas and the Stream API through a simple game. • • Get to know lambda expressions in Java 8. • • Learn how to use lambda expressions to your advantage. • • • Java Chief Language Architect Brian Goetz takes on the question of why lambda expressions took so long to implement and how lambdas will impact developers. • • Lambdas introduce a powerful Inversion of Control in Java – allowing a clear and elegant distinction between the what [should be done] and how [should it be done]. Under certain circumstances Java is very similar to SQL! • • • • This book shows you how to make use of your existing skills to adapt your thinking and codebase to use Lambda expressions properly. • • What can Compact Profiles do for your application? • • Compact Profiles have a smaller storage footprint to enable many Java applications to run on resource-constrained devices. • • Java 8 will define...
