Is there Java or openJDK in the package, when installing Ubuntu Mate? I can see a Java softlink, Java directory with some jar files, but if trying to run something which needs Java, it seems there is no Java.
Hello Juandev
You can install jdk-packages via the package manager Synaptic. You should also be able to see if any "jdk" packages are already installed.
You can install Synaptic via the command line, something like sudo apt install synaptic should do the trick. 
So this means, there is no Java in Ubuntu package?
Hi @Juandev,
you can check preinstalled packages in manifest file. Looks like there is no JRE preinstalled.
