debian install jdk 

    

  • sudo apt-get install software-properties-common

    •
When prompted to confirm the installation, type y for yes.
To ensure that we get the correct source line on Debian, we’ll need to run the following command that also modifies the line:
    

  • sudo add-apt-repository "deb http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main"

    •
Once we do that we’ll need to update:
    

  • sudo apt-get update

    •
Now we’ll go through the installation process of different versions of Java. You can decide which versions you would like to install, and can choose to install one or several. Because it’s the latest stable release, Oracle JDK 8 is the recommended version at the time of writing.
