Every modern software development stack has one or more well-known common libraries which is not a part of the language core. On the other hand, such general purpose package extends standard set of methods and data structures to professional level of software development. E.g., STL for C++ world. Apache Commons [https://commons.apache.org] is one of the most useful set of general libraries in Java Development. A lot of other packages and frameworks are based on them. In case of new project, Iflexion developers, first of all, to look at Guava [https://code.google.com/p/guava-libraries] — a modern professional implementation of common methods.
Guava is done by Google, freely distributed and supported by Internet giant. They even claim Guava usage in their own projects as a standard. There are 3 main programming languages are used in Google: Java, C++ and Python. Guava is based on Java 6. That makes it useful in legacy projects implemented in terms of Java 6 and needed to support this version. E.g., strings join may be done in Java 8 as String.join(“, “, strings) or by Guava Joiner.on(“, “).join(strings). Guava modules are created with design patterns in mind. There are builders, factory methods, adapters, etc. Guava available via maven/gradle. E.g., for gradle:
Callbacks and other approaches
The simplest native way to deal with asynchronous code is to use callbacks. It may be ok in case of small application or use case. On the other hand, in real life Application Development, Iflexion company have complicated huge solutions splitted into many modules and layers. To use pure callbacks in this situation is antipattern.
There are several powerful technological stacks available to create any kind of web application from a set of microservices with REST API to huge enterprise solutions. They a based on appropriate programming language as a platform, like Java, C#.NET, Python, PHP, etc. All those web development platforms are completely separated. They are rather linked and even much more than you ever imagine. Trends are popular in one platform found their mirror in another and vice versa. That’s mostly because of enthusiastic activity of multi-platforms software developers. E.g., a lot of Java Development packages and approaches are converted into their C#.NET clones almost one-to-one with adding a .NET suffix.
Another example of multi-platform web development approach is micro frameworks. These are very light MVC frameworks that provides basic web application functionality out of the box. On the other hand, they need minimal code and development efforts as a whole to implement and launch ready to use application. PHP has Slim, Limonade, Lumen, Flight, Silex. Sinatra is the most popular Ruby micro-framework. Flask is for Python stack. For Java Development there is a Spark [http://sparkjava.com/].
10 years ago, Spring framework became a trend in Enterprise Java Development without huge and overweight classic JEE (it was called J2EE) technology based on EJB. We called Spring as JEE without EJB. Its amazing IoC container and DI schema have been doing our life much more easy. Configuration via annotations made the whole process even more fun, because it allows us to avoid describing all our beans and relations in XML. Nowadays, modern popular frameworks like Ruby on Rails or Django provides even more fast tools and development practices. On the other hand, Java Development world is bit more conservative. We had no easy and fast way to start new project. Instead, we had to spend some time to configure Spring environment. Spring Boot [http://projects.spring.io/spring-boot] is a solution for this problem, applicable in case of start up, agile approaches or even pet projects.
Configuration over dependencies
Rail uses its power command line tools to start new application, generate new element of the project and various other actions. But Spring Boot is not an automatic code generation tool. It is rather a plug for Java Development build system. It supports both Maven and Gradle. Main feature of of Spring Boot is
The brand new Java 8 is finally on the market! That’s what a lot of java web programmers waited for. For its’ release Oracle offered so called LDK8 also known as Java Development Kit. The java developers from Iflexion feel the descent shift new Java represents with its completely new approach.
Java 8 – what’s it all about?
YoavLandman, the primary Java developer, is really happy and proud of company’s new creation. “Now you can code in totally new way. Be ready for greater options!”
Due to the new methods used to create the perspective functional paradigm in order to replace an old imperative paradigm new Java 8 will offer comfortable solutions for developers. All bugs appear to be not only easily to track, but also handy to fix. Any problem can now be decomposed in any functional value. A lot of tools can now be used for the purpose to manage binaries.
These breaking news have shocked the IT world! New programming issue threatens to beat up the main software programming languages like PHP, Ruby on Rails and even Java!
This fresh newcomer is Node.js and it offers some brand new features that will most likely be handy for newbies as well as for those who tend to work with over-complicated systems.
The main problem of Java developers
Each Java development company employee sometimes comes across the trouble of system being too complicated. Their script might not work correctly or may just not work at all, let along the fact that any operation takes forever to be completed.
The great possibility for Java outsourcing appeared in 2001 at the time or Eclipse creation. In March-May 2005 over 17.000 copies were downloaded by the users every single day! The product got the great attention from authors, providers, bloggers and even developers. The great popularity of Eclipse was formed for due to it being the perfect platform for developing Java applications.
We’re now going to talk about the latest Eclipse platform version 3.1. It can be easily downloaded from the official site and has a lot of useful features to offer.
Does Java outsourcing get the new hope?
The most important brand new feature of new Eclipse is its support of new languages. This scheme is well known as J2SE 1.5 orJ2SE 5.0. This is the great source of whole new options for IT stuff.
Trying to fix out what’s new in Java is much like trying to follow the cat – it just goes anywhere it wants, digging into whatever comes on its way. Same goes with Java that appears to be fully integrated in all kinds of mobile, cloud and other related spaces.
What we’re trying to do is to figure out the most visible paths Java is going to take in 2013.
Oracle appeared to be really linked with Java in most possible ways. This means application developers soon will have to cope not only with Java’s bugs, but with Oracle bad features as well. That’s what you shall get ready for right now. Also the credibility of Java has been severely damaged through its lack of security features we all could see in Java 7. This all led to the real bunch of users switching off Java.
Be aware of the best Java trends offered on the IT market
If you’re the programmer, no matter of your qualification and specialties of your business you must keep an eye on the newest programming sweets offered on the market. In the world of Java things are changing rapidly, so you shall always keep a close eye on what’s happening there. There is so much news concerning Java development that one day you way feel yourself the first grade pupil surrounded with things you have no idea about. That is why our primary goal is to enlighten the latest trends of Java.
Trend #1: JVM is no more for Java
People realize that VM can now be used with any language they feel comfortable with. Some of them create their own languages; still the best option is to concentrate on syntactic bells and structural whistles.
The definite extend of the information hiding is known as scoping. This is the way to show the variables and methods. The systemized approach is granted here by Java as it allows it to be organized and expressive.
You can see the variables gathered in a scope. The single ones will get called “namespace”. With their help you will be able to associate them with the scopes during java programming. There are easy ways to use namespaces, for example the developer can be sure the variables always stay in their section and do not interfere with the other. Several developers can work on the same project at the same time and even use the same variables, still they will not get their programs interfered.
Here are three basic things the scopes do:
- Contain variables
- Contain methods
- Nest and be nested
