Hi,

I have a program which uses quite a lot of memory so
I can not use the default maximum heap size.
Instead, I supply the parameter '-Xmx160m' to java,
giving the VM a maximum heap size of 160MB.

Now, when I use 'Runtime.getRuntime().totalMemory()'
it returns 2031616. This is not what I expect for it is
approximately 2MB.

My question is: Have I supplied the wrong parameter
to the JVM or do I not understand the method
totalMemory()?

Thanks,
Ronald.
