In this chapter from Core Java for the Impatient, you will learn about interfaces and lambda expressions, including static and default methods, method and constructor references, processing lambda expressions, variable scope, higher-order functions, and local inner classes.

Voilà bien un sujet sur lequel j’ai adopté (une fois encore) la position du sceptique. Quand on m’a exposé l’idée de l’inversion de contrôle, j’ai trouvé que c’était un point de vue intéressant mais sans plus. Quand j’ai commencé à voir les premiers fichiers de configuration Spring en XML, j’ai écarquillé les yeux… Constater qu’une partie de mon code Java, organisé, compilé et déboguable, devait se retrouver sous forme déstructurée dans du XML peu lisible et mal contrôlé, ne m’a simplement pas emballé. Ce constat n’a pas empêché une flopée de développeurs de faire du Spring à fond les manettes, persuadés d’adhérer à une innovation majeure, avec parfois une pointe de dédain envers ceux qui n’en faisaient pas !

Of the SOLID principles, made famous by Robert C. Martin, we'll discuss the Single Responsibility Principle and the Open/Closed Principle, two of the presenter's favorite principles. But at the same time the least understood and used principles. That's why this session will explain them thoroughly and give real life examples instead of the regular customer & order examples. You'll walk away knowing what the benefits are and how to use them properly.

The following article aims to explain the five SOLID principles with real world examples. The SOLID principles are five programming principles which is considered to be the foundation of every well designed application. Following the principles will most likely lead to applications which are is easy to extend and maintain. That’s possible since you got small well defined classes with clear contracts.

The first five principles are principles of class design. They are:
SRP The Single Responsibility Principle A class should have one, and only one, reason to change.
OCP The Open Closed Principle You should be able to extend a classes behavior, without modifying it.
LSP The Liskov Substitution Principle Derived classes must be substitutable for their base classes.
ISP The Interface Segregation Principle Make fine grained interfaces that are client specific.
DIP The Dependency Inversion Principle Depend on abstractions, not on concretions.
The next six principles are about packages. In this context a package is a binary deliverable like a .jar file, or a dll as opposed to a namespace like a java package or a C++ namespace.
The first three package principles are about package cohesion, they tell us what to put inside packages:
REP The Release Reuse Equivalency Principle The granule of reuse is the granule of release.
CCP The Common Closure Principle Classes that change together are packaged together.
CRP The Common Reuse Principle Classes that are used together are packaged together.
The last three principles are about the couplings between packages, and talk about metrics that evaluate the package structure of a system.
ADP The Acyclic Dependencies Principle The dependency graph of packages must have no cycles.
SDP The Stable Dependencies Principle Depend in the direction of stability.
SAP The Stable Abstractions Principle Abstractness increases with stability.

This website provides a palette of patterns you can use in the context of designing Java 2 Platform, Enteprise Edition (J2EE) applications. Occasionally, new patterns will be added and new insights will be incorporated into the current patterns, so check back often for updates. The BluePrints patterns catalog is based around the Sun Java Center patterns catalog, described in the Core J2EE Patternsbook by Deepak Alur, John Crupi, and Dan Malks.

“Central”, “Maven Central”, “The Central Repository”. Vous rencontrez fréquemment ces termes dans le monde du développement Java open source. La plupart des collaborateurs de Sonatype pensent que tout le monde sait de quoi on parle lorsque l’on évoque « Central ». Comme ce n’est pas toujours le cas, cette vidéo vous donnera un aperçu de Central et ce qu’il représente pour la communauté Java. Bon visionnage !

L'injection de dépendances est souvent la base de tout programme moderne. L'idée en résumé est de déporter la responsabilité de la liaison des composants du programme dans un framework afin de pouvoir facilement changer ces composants ou leur comportement. Parmi les leaders du marché Java, il y a Spring IoC, Guice, Dagger… ou encore le standard « Java EE » CDI qui existe depuis Java EE 6. Ce dernier s'est inspiré de plusieurs standards de facto, pour finalement devenir aujourd'hui la base de la plateforme Java EE moderne. Ce tutoriel vous propose un tour d'horizon des fonctionnalités de base de CDI.

I stumbled across Uncle Bob’s SOLID principles of OOD quite a few years ago. They serve as the foundation of knowledge for designing object-oriented software. In fact, if you analyze the GOF patterns, you’ll find that virtually all of them adhere to the class design principles. I felt strongly enough about these principles that I included them in Chapter 1 of JOUP.
When used judiciously, they serve as excellent guidance in designing object-oriented software. But it’s not the SOLID class design principles I want to talk about here, at least not exclusively. Instead, it’s their less famous brethren that are often lost in the discussion of the SOLID class design principles…the principles of package design that I want to discuss.

Most professional software developers understand the academic definitions of coupling, cohesion, and encapsulation. However, many developers do not understand how to achieve the benefits of low coupling, high cohesion and strong encapsulation, as outlined in this article. Fortunately, others have created stepping stones that lead to these goals,
resulting in software that is easier to read, easier to understand and easier to change. In this article series, I will define three of the primary object-oriented principles and show how to reach them through the five S.O.L.I.D. design principles.

Emergent design can quickly degrade into un-maintainable hack & slash yuckness without a set of guiding principles to keep you in check. Fortunately, Robert Martin’s SOLID Principles are just what the doctor ordered for saving your app from an early demise.
