I need Java 6 in order to run some other programs. When I installed OS 10.13.2, it apparently deleted Java 6 and replaced it with a new version. Now when I try to re-install Java 6, I get a message saying that it will not install because a newer version of Java is installed. I have tried to un-install the current version of Java that is on my computer, but I get a message saying it cannot be uninstalled because it is required by the system. Is there any work-around that would enable me to install Java 6?
