Answer 1

Either you don’t have java or its not available in your path. Some linux distros install java in the /opt directory. So be sure to check if that’s the case with you. If so then its just a matter of updating your path if not then there are two possibilities :
1. You have root access.
2. You don’t have root access.

If you do have root access then you can easily install java with your package manager, if now you can still install java as a local user. Read this to do that. You can install any version of java that you so wish, also it may be unnecessary to install JDK, just JRE might be enough for you.
Don’t do the steps that need root access, just copy it somewhere in your home directory or any of the directories to which you have access. Then set the appropriate values for JAVA_HOME and your PATH. It should work then.
If you need any help in doing that feel free to ask.
