I believe, newer versions of Weka have been bundled with a Java
runtime environment.
But yes, you can install your own Java version(s).

I'm not sure whether you have administrator level access on your
machine, so here is a post that I wrote the other day on how to
install Java without requiring admin rights:
https://adams.cms.waikato.ac.nz/posts/windows-no-admin-no-problem/

That approach (via the JAVA_HOME environment variable) also has the
added benefit that you have multiple Java versions present in parallel
and you can simply switch between them by updating the environment
variable.
