    Sorry, but we can't help you if you don't answer our questions. If you don't know how to get a specific information, ask that. However, you have been simply asked for the output of javac - that means you open a terminal (CTRL+ALT+T), type javac, hit ENTER, select the output text with your mouse, right-click on it, select "Copy" from the appearing context menu, click the edit link below your question, paste your command output at the end of it, select it again in the question editor ad press CTRL+K to format it properly.

    And please try to improve your language a bit, sometimes it's quite hard to understand what you want to say... Translation services like translate.google.com might help you. Thanks.

From your error message, I can guess that you wanted to install oracle-java-8 and for any reason that installation wasn't successful or half-broken now. So, I suggest installing these to run scala-2.11.6 on Ubuntu 16.04.

  1. First install java

    sudo apt install openjdk-8-jdk
  2. Then install scala

    sudo apt install scala

The repository for Ubuntu 16.04 has scala verson 2.11.6 and I've installed it and tested without any problem.

If you face further problem, edit your question describing how the answer didn't help.

  1. First, install JDK

    sudo apt install default-jdk

  2. Install scala

    sudo apt-get install scala

    scala -version

  • Yes, almost the same answer, but here's default-jdk used instead of openjdk-8-jdk and it seems they are independent. I have both installed.
