How can I determine the JVM minimum heap size from within a java application?

Question

I have reviewed the answer to how to get the min and max heap size settings of a JVM from within a Java program which was helpful, but the accepted answer doesn't appear to answer half of the question. In essence, I want to report the -Xms and -Xmx settings that were used when the JVM was launched.

Answer 1

These are the mappings between values you're looking for:

-Xmx=Runtime.getRuntime().maxMemory()
-Xms=Runtime.getRuntime().totalMemory()

Hope this helps.
