For example, in the case of Java it is more useful to learn how to use Netbeans or Eclipse and use Oracle's Java. The compatibility between the two is 99,9 percent, but personally I think that for a training that makes things easier for us if we want to work in the company it is convenient to adapt as much as possible to the official tools. Now let's see how to install java on Ubuntu, something that is not entirely complicated, although it does require some steps that should be clear, especially since we also currently have the possibility of installing both the version of Oracle's Java -that is, the official one- and OpenJDK, which is developed by the community and that began as a bet for the future when it was not clear what Java's role would be in terms of its attitude towards it. And in some quite notorious cases like that of Ubuntu, we have to take a few laps to install both the Java runtime and its SDK if we prefer (or need to start developing code). In this clear case, with arrival to many distros, although not all package systems incorporate it in a friendly way or offer the newest versions. That is how Java made it to the major operating systems like Windows, Mac OS X (at that time, MacOS) and of course Linux.

The idea was to develop applications that could be created in any operating system that has Java support and then be executed in any other without the need for modifications, which in the jargon was known as WORA ('write once run anywhere', or ' write once, execute anywhere »). Java was developed by Sun (now owned by Oracle) back in 1992, and arose from the need to create a platform that would allow the development of universal source code.
