I've updated to JDK 9, but some users of my apps report that application does not start up (they have Java 7).
How can I compile my code the way it will be compatible with Java 7? I am using Eclipse.
EDIT : It's not a duplicate. The question you are referring to does NOT answer my question. I can edit environments, but I don't think that using JDK 9.0.1
as JDK 1.7
would actually compile under 1.7
.
