Usually we store those shell scripts under /usr/lib/jvm/tools. This one is called removeDefaultJavaAlternatives.sh.
Don't forget to chmod your shell script.

As you've uninstalled a JVM, it depends whether or not you have other installed JVM. In case you have more than one, the update-alternatives will update your configuration with the highest priority JVM.
Then check again that everything is correct with your Java Update Alternatives Environment.
