Programming

I thought some of you might be interested in hearing about Java and the Java dev team at a startup that's grown beyond the initial stage. Nexmo is a four year old startup headquartered in San Francisco but with the engineering team based out of techhub London; and is already one of the worlds largest cloud communications companies (cloud communications provides any application with the ability to...

As you may already know, Java's Stream API is one of the most significant features introduced in the latest platform version. Aside from the lambdas, which can reduce the amount of boilerplate code in our code base, the Stream API releases us from the burden to be responsible for how collections are traversed, for example. In the pre-Java8 platform versions, we could either use an implementation...

EJB

I've just finished tuning a client's application where one of the items on the table was to find the source of calls to System.gc(). Using Censum made easy work of understanding the source of the calls. The team I was working with not only missed that these calls to System.gc() where creating havoc with their end users experience, they didn't even realize that something, some where was messing...

Web Development Tools

Bunyan is a NodeJS library that rethinks logging in some really useful ways. I wrote a Java port you can use in your applications. In particular, with Bunyan, logs are JSON - and Bunyan comes with a great filtering and analysis tool. The Java port uses some innovative techniques to make logging simple and foolproof - in particular, a use of AutoCloseable to make a logging code simple and...

Since begin of the time, the man need to do exchanges of goods materials or services, began with simples goods exchanges. In this time, already has necessity to start the standardization process, the first step was using metals as gold, silver and bronze becoming to representative money today. Nowadays with large number of e-commerce and automation of finance market and another systems that take...

Introduction to Class Diagram In any project's planning phase, the programmer should describe the behaviour of the different objects that are required to satisfy business use cases. However objects can't emerge from nothing, so you need a template that describe the type of objects that the system will have. As a result, you will need to show a diagram with all the classes involved and their...

Why do we need to program? Technology is part of our life. The world is changing daily and everything is getting automated. Learn to program is the creative way we can take our ideas to the next level and express solutions to society. By designing programs, we learn several abilities like critical reading, analytical thinking and create synthesis. The programmer defines the problem, plans a...

The Java is a platform which grown up quickly, for many rations such it can write once time and run anywhere, it runs languages on JVM. There is a myth that Java cannot compile its sources on run time, but it's truth? Have a dynamic language is important to make some projects, for example, calculate taxes to different cities, so the source should be on the database and each city it puts the...

HTML Online Editor Sample I have been contemplating for a number of months about reviewing a cache of articles and videos on topics like Performance tuning, JVM, GC in Java, Mechanical Sympathy, etc... and finally took the time to do it - may be this was the point in my intellectual progress when was I required to do such a thing! Thanks to Attila-Mihaly for giving me the...

Databases

Redis is a NOSQL database written in C. The Remote Dictionary Server is a key-value data base whose the storage is in memory, then the write and read will fastest way, but which difference between Redis and Cache? What does happen when the database fall down? Will we lost the all informations? The main goal of this article is talk about the Redis and show an open source project, the redis-...

JDK 8 introduced a lot of new features and improvements in the platform from Lamda expressions, Stream collection types, Functional interfaces, Type annotations, Nashorn etc. Guava library from Google provided some support for functional programming idioms prior to JDK 8. I have been using Guava for some of my projects. So here is a small write up on how new functionality added in JDK 8 makes it...

The lambdas are without any doubt one of the most intriguing and attractive features in Java8, but sometimes instead of helping us writting a better and boilerplateless code, they can get us into trouble. And still, they are the better alternative to the anonymous classes for lots of reasons. The anonymous classes were a nice way to achieve clojures in Java, but it was something natural to...

Runtime type information (RTTI) refers to the correct identification of the type of your objects at run time. When you write code, it is generally desirable to do so in a way that takes advantage of OOP features like encapsulation and inheritance to make your program easily extensible, by for instance, as much as possible manipulating references to base classes and letting polymorphism work for...

In this post, I try to give a reasonable account of Java's error handling system being as it is that the handling of errors is a concern that any reasonable programming language must find some way to contend with. Java's error handling methodology is based on an idea of exceptions. An exception is a condition that prevents your program from further executing along the current path. It signifies...

If you have followed previous posts, you might begin to perceive a pattern in the semantics of the Java programming language. If not, it might help to go over previous posts as I tend to return to expand on previous topics or add clearer examples as time permits. Inner classes might at first seem like a whole new language to the uninitiated but they are a nice feature in Java that allow you to...

In the normal course of solving a general programming problem, it is almost certain that you will become compelled to create, and identify useful ways by which to hold any number of objects within your program. In Java, you are normally inclined toward the array as the natural choice for holding a group of primitives, but this has the obvious limitation of being of a fixed size, whereas, under...

Interfaces are completely abstract classes in Java that provide you with a uniform way to properly delineate the structure or inner workings of your program from its publicly available interface, with the consequence being a greater amount of flexibility and reusable code as well as more control over how you create and interact with other classes. More precisely, they are a special construct in...
