Multimedia components and proprietary programs

The New Java
To use Java applications, you need a Java Runtime Environment (JRE). Ubuntu does not provide Oracle's proprietary Java version anymore – only the free OpenJDK. Because some Java programs had problems in the past with OpenJDK, many users often resorted to the proprietary Java (sun-java ). But, that's missing now because Oracle put it under a non-free license. Because the proprietary Java is compatible with OpenJDK 8 – the official Java reference – most Java programs should be able to make do with the free Java. You can install the software from the openjdk-8-jdk and icedtea-8-plugin packages, and the older version from openjdk-7-jdk and icedtea-7-plugin via the following command:
$ sudo update-alternatives --config java
This step activates one of the parallel installed Java versions. If an app refuses to run, it's best to submit a bug report at the Ubuntu wiki [8].
Seek and You Shall Find
You can install many proprietary apps and multimedia codecs from the existing repositories. Numerous proprietary Windows programs also run in the Wine Windows-compatible environment [9]. Other than that, take a look in the Ubuntu package manager, because almost any application has a free alternative.
