This article mainly shows you what are the hot spots related to Java in 2014, which are easy to understand and well-organized. I hope it can help you solve your doubts. Let's take you to study and learn the article "what are the hotspots related to Java in 2014".

1. The Internet of things has become a reality

As long as you attended a separate meeting or searched a dedicated technology website last year, you will now notice more and more clearly that the Internet of things is booming. If the most exaggerated predictions come true, there will be a billion devices fully interconnected in the market by 2018. In our opinion, there will be at least a few million units-in any case, it is enough to inspire potential "gold prospectors" in this market.

There has been a lot of verbal recognition of the Internet of things on JavaOne, and there will only be more heated discussions in 2014. In 2014, we look forward to actively promoting industry differentiation (focusing on the same thing from different perspectives), and we learned from the ThingMonk meeting in December that we need to pay more attention to design. Not only will we cherish the achievements of others more, but everyone can also share their own opinions.

2. Multilingual renaissance

Since the introduction of the invokedynamic directive in Java 7, invokedynamic has been introduced in JSR 292 to bring good news to Java dynamic language development. Languages based on Java virtual machines have grown like the Cambrian explosion. Clojure and Scala have become alternatives to Java; even without JVM, there is a similar trend in other industries to fully exploit the strengths and weaknesses of different languages-thanks to the evolution from holistic single-platform applications to component-based architectures. There is no better hope in this pluralistic revolution than Vert.x, which can use Node.js in any language.

3 、 Java 8

When will the next Java8 launch be announced? Java SE 8 was supposed to arrive in 2012 and will include features that Java 7 should have but not yet released. But in the end, the release was delayed, and some of the planned features were even cut. Two years later, the long-awaited update should be released on March 18. The Lambda project introduces closure syntax for Java, and Java 8 includes a new date and time API, a new JavaScript engine called Nashorn (rhinoceros), new type annotations, and more compact configuration files. With the release of the Java 8 developer preview, there are strong signs (hopefully not ominous) that Java 8 will see the dawn in 2014.

4. Java development has become (gradually) more open.

Since the emergence of Java, Sun (later Oracle) has played a leading role in the development of the whole language. In spite of this, the development process of the Java language is still democratic and progressing. In the past few years, many meaningful changes have taken place in the Java development process, largely driven by a large number of user groups, such as the Java community in London and SouJava in Brazil. The Adopt-A-JSR mechanism, which encourages community members to provide detailed feedback on Java functionality, has been very successful and even Oracle has readily adopted it.

5. Programming has become a fashion

It's not just Java, but as fashion technology startups and so-called hacker culture begin to enter the mainstream (through the movie "Social networking" and another possible TV show about the origins of Twitter). Engaging in this kind of technical work is not as humiliating in society as it used to be. Code.org and Railsgirls take the lead in guiding children to program, and many companies like Codecademy make it easier for people to learn the basics of programming. All this means that many potentially talented programmers have been unearthed, and then they have created richer new ideas and methods.

What are the commonly used java frameworks? 1. Spring Web Web MVC is a Java-based lightweight Web framework that implements the request-driven type of Spring design pattern. 2. Shirojia Apache Shiro is a security framework for Java. 3. Mybatistion MyBatis is an excellent persistence layer framework that supports normal SQL queries, stored procedures and advanced mapping. 4. DubboPol Dubbo is a distributed service framework. 5. Mavenfine Maven is a project management and build automation tool. 6. RabbitMQ _ RabbitMQ is a highly concurrent and reliable AMQP message queuing server implemented with Erlang. 7. EhcacheJournal EhCache is a pure Java in-process caching framework.
