With Java supporting lambda expressions, we have nothing to stop us from creating functional style of code for our day to day applications. We are so used to object-oriented programming, but remember the paradigm shift we went through to adapt to that way of programming. It is yet another paradigm shift and most of us wonder how in the world can we write functional style code. Much like how OO was not as much about the syntax as it was about the design, functional programming is about the design, the idioms, and the data structures we would use to program.
In this hands-on workshop, we will learn about functional programming using practical examples, create small apps that will make use of this style of programming, and relate to how it differs from the traditional way were used to and the benefits it offers.
Workshop Requirements
This session is a workshop. Please come prepared. Please have the latest version of Java 8 installed along with JUnit. Also, have svn or git-svn installed to get access to example and lab code during the workshop.
The new facilities in Java 8 is about the change the way we write code. Our code will become
more expressive and concise. But, exactly how?
In this presentation we will take several common Java code examples, discuss the core idea expressed in code, and transform that code to use the facilities in Java 8. Watch and interact as you see Java code go through a weight loss program right in front of your eyes.
Organizations have moved from making their employees available to having their applications available directly to the users. This changes the magnitude of scale
of interactions the applications have to support. Furthermore, with devices and bots accessing the systems, we’re looking at a complete different rate of response than we once had to aim for.
In this presentation we will discuss the fundamentals of reactive systems, the key design goals, and the technologies that facilitate building such systems.
We all have heard about lambda expressions in Java 8. The real unsung hero of Java 8 are the Streams.
In this presentation we will take an example driven approach to explore streams, their core capabilities form the application development point of view, and how to explore these capabilities for improve performance and efficiency.
Big up front design is discouraged in agile development. However, we know that architecture plays a significant part in software systems. Evolving architecture during the development of an application seems to be a risky business.
In this presentation we will discuss the reasons to evolve the architecture, some of the core principles that can help us develop in such a manner, and the ways to minimize the risk and succeed in creating a practical and useful architecture.
Creating code is easy, creating good code takes a lot of time, effort, discipline, and commitment. The code we create are truly the manifestations of our designs. Creating a lightweight design can help make the code more extensible and reusable.
In this presentation we will take an example oriented approach to look at some core design principles that can help us create better design and more maintainable code.
