I'm trying to unblock MC on my school mac and

I'm trying to unblock MC on my school mac and I already unblocked the app
but I can't launch due to the mac's not having Java we can't install or
launch unauthoized programs so is there a way I can bind java just to that
folder or program? (Do NOT Say Mine+CRA+FT because then the page will be
blocked.)
