Announcing .. Gradle Tutorial Series Welcome to a new blog series where I aim to cover the basics of Gradle, the build tool that not just everyone is talking about but adopting widely. Companies, small and large have adopted this tool and while you might be familiar with Ant and Maven, it is time to take a look at Gradle. The need for writing this series has come about primarily due to my work with a few Google related technologies/frameworks. I use the Google Cloud Platform widely for my projects (both professional and hobby) and have primarily used Eclipse as my IDE for both Cloud Projects (running on Google App Engine) and front-end mobile applications (Android).

Generifying your Design Patterns Generifying your Design Patterns Part I: The Visitor by Mark Spritzler In the upcoming months, I will be writing a series of articles on Generifying your Design Patterns. We will look at a number of Design Patterns from Singleton, Factory, Command, Visitor, and the Template Method. Yet Another JUnit Tutorial - JUnit in a Nutshell JUnit seems to be the most popular testing tool for developers within the Java world. So it is no wonder that there have been written some good books about this topic. But I still meet quite often programmers, who at most have a vague understanding of the tool and its proper usage. Hence I had the idea to write a couple of posts that introduce the essential techniques from my point of view. The intention is to provide a reasonable starting point, but avoid daunting information flooding à la xUnit Test Patterns.

Lesson: Generics (Updated) (The Java™ Tutorials > Learning the Java Language) In any nontrivial software project, bugs are simply a fact of life. Careful planning, programming, and testing can help reduce their pervasiveness, but somehow, somewhere, they'll always find a way to creep into your code. This becomes especially apparent as new features are introduced and your code base grows in size and complexity. Fortunately, some bugs are easier to detect than others. The Java™ Tutorials The Java Tutorials are practical guides for programmers who want to use the Java programming language to create applications. They include hundreds of complete, working examples, and dozens of lessons. Groups of related lessons are organized into "trails". The Java Tutorials primarily describe features in Java SE 8. For best results, download JDK 8. What's New

Java Tutorial Java is a high-level programming language originally developed by Sun Microsystems and released in 1995. Java runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. This tutorial gives a complete understanding of Java. This reference will take you through simple and practical approach while learning Java Programming language. This reference has been prepared for the beginners to help them understand the basic to advanced concepts related to Java Programming language. Before you start doing practice with various types of examples given in this reference, I'm making an assumption that you are already aware about what is a computer program and what is a computer programming language? Java 8 Lambdas - A Peek Under the Hood Java 8 was released in March 2014 and introduced lambda expressions as its flagship feature. You may already be using them in your code base to write more concise and flexible code. For example, you can combine lambda expressions with the new Streams API to express rich data processing queries: int total = invoices.stream() .filter(inv -> inv.getMonth() == Month.JULY) .mapToInt(Invoice::getAmount) .sum();
