What is the best way to verify default heap size in Java

What is the best way to verify default heap size in Java ? does it vary over JVM to JVM . I was reading this article http://javarevisited.blogspot.sg/2011/05/java-heap-space-memory-size-jvm.html , and it says default size is 128 MB but When I run following code :
public static void main(String args[]) {
int MB = 1024*1024;
System.out.println(Runtime.getRuntime().totalMemory()/MB);
}
It print "870" i.e. 870 MB.
I am bit confused, what is the best way to verify default heap size in any JVM ?
