passing same jre options with different values

[D Preethi]

Hi All,

I have a basic question to ask. I have a java application, for which there are multiple places where the jre memory options can be passed. So, if I end up with a command line like this:
java -Xms=512m -Xmx=512m -Xms=128m

I wanted to know which of the Xms value is honored? 128 or 512? Is there a way I can check this?


Thanks,
Preethi

Would this work?

long heapSize = Runtime.getRuntime().totalMemory();
         
System.out.println("Heap Size = " + heapSize);

There are couple of other methods in the Runtime class:

freeMemory()
maxMemory()

You can do the math, I guess
