The arrival of the http protocol and the Mosaic browser
In 1993, we witness the arrival of the http protocol and the Mosaic browser , which was a crucial event for the project. It was during this period that the team realized that the Internet would be the ideal network to position their product. In 1995, James Gosling unveiled a browser called WebRunner capable of showing html content mixed with applets (= small application that is downloaded when visiting certain websites). The success was in progress as the threshold of 10,000 downloads was quickly reached. Things are taking their course: WebRunner becomes HotJava and the site java.sun.comofficially opens to the general public. Finally, the name of this technology will be Java (coffee in American slang) , in honor of the favorite drink of programmers, that is to say coffee , part of the production of which comes from the island of Java . It was then that Sun and Netscape announced their desire to integrate Java technology into their browser, which definitively launched the language. The versions will then follow one another from Java 2 in 1998 to Java 9 in 2016 .
The first concern of the designers of Java was the possibility of executing the same Java code on any machine or under any OS . The goal is to be able to download Java applets through the Internet and to be able to run them in your own browser. This is what will make the very strength of the Java language: its absolute compatibility . So, it would be quite possible to compile a Java program on a Windows machine, and run this code on a Macintosh. From version 2 to version 6 of Java, the Sun company released a major version of Java every two years, except between Java 6 and Java 7 (4 years). This dual wait between these two versions is explained by the fact that Sun was in a very bad financial situation in 2009. Year in which Oracle will acquire Sun . The buyout process is very long and will take a year. A year during which the development of the Java platform hardly progresses . The releases of Java are therefore disrupted by this takeover, and version 7 of Java did not come out until 2011. It will be noted that over the course of the different versions, the fundamental aspects of the language have changed little, even if they have been nonetheless. substantially supplemented by Java 5. However, the standard libraries(API) have evolved a lot, with many additions and modifications. The sets of specifications accompanying each standard version of Java have also evolved significantly (J2EE up to version 4 and JEE from version 5).
Why is Java so popular?
This language is popular mainly because it is the basis for most network applications . This technology is used around the world to develop and deliver mobile and nested applications, games, web content, and business software. There are currently 9 million Java developers worldwide who use this technology to effectively develop and deploy applications and services of all kinds. From laptops to data centers, from game consoles to scientific supercomputers, from cell phones to the Internet, Java technology is present in every field .
From Oracle data:
- 97% of corporate offices are running Java
- 89% of offices (or computers) in the United States are running Java
- 9 million Java developers worldwide
- # 1 developer choice
- Development platform n ° 1
- 3 billion mobile phones run Java
- 100% of Blu-ray players come with Java
- 5 billion Java cards used
- 125 million TV devices run Java
- Top 5 Original Equipment Manufacturers Provide Java ME
Other reasons for this popularity
The Java language is object oriented . This makes the codes heavier at design but much more structured and maintainable later. Java has very handy APIs like string manipulation, image / sprite manipulation etc… It is a perfect language for a beginner which makes it so popular. Indeed, Java is a so-called “high level” language, that is to say that we do not worry about how to manage memory as with the C language for example. Everything is done “automatically”.
The Java language allows some part of the code to be compiled into native code for better performance . The Java APIs also have good documentation on the net and the Java community is of course huge. All this makes Java a very popular and widely used language, especially as it is constantly evolving due to its large user base.
Eternal leader of the Tiobe index for years
The Tiobe index measures the popularity of each language each month by operating on the basis of the number of web pages returned by a search engine, when the name of the programming language is submitted to it. A language that is talked about a lot on the net will therefore be a “popular” language for TIOBE. This index does not take into account the direct number of users of a language but rather the interaction that the language exudes on the Internet and the discussions that result from it. This popularity measured by Tiobe takes the form of a ranking of languages each month. The Java language itself is at the top of the rankingfor years, since the amount of information about him is absolutely gigantic. It should be noted however, that the C language , which is similar to Java in its syntax, has a strong progression in the Tiobe index and is gradually getting closer to its Java colleague over time.
