I'm not sure that this is the right forum to post this on, but after taking a look at several other forums I haven't been able to find one that really seems to fit.

I just now applied for a Software Developer position. The job description listed as a qualification, "Familiarity with Java tools and the JRE." How does one go about getting familiarity with Java tools and the JRE? Any information on this would be greatly appreciated.

It's a little vague which may mean that the person who wrote the job spec, a recruiter perhaps, doesn't really know either.

I'd expect they're talking about things like JMX and how to connect a debugger to a running JVM. That sort of thing.

Perhaps also may include knowledge of JVM tuning such as the GC and Memory usage settings.

How would I find out the details on the GC and Memory usage settings?

I'm sure some internet searching would throw up endless resources for your consumption.

I would always recommend Martin Thompson to explain complex topics in simple language: https://mechanical-sympathy.blogspot.co.uk/2013/07/java-garbage-collection-distilled.html. That said, I have a feeling the GC operation has changed in Java8 or is changing in Java9, I forget which.
 
It is sorta covered in the JavaRanch Style Guide.
