java memory usage
- by xdevel2000
I know I always post a similar question about array memory usage but now I want post the question more specific.
After I read this article: http://www.javamex.com/tutorials/memory/object_memory_usage.shtml
I didn't understand some things:
the size of a data type is always the
same also on different platform
(Linux / Windows 32 / 64 bit)???
so an int will be always 32 bit?;
when I compute the memory usage I
must put also the reference value
itself? If I have an object to a
class that has an int field its
memory will be 12 (object header) + 4
reference + 4 (the int field) + 3
(padding) = 24 bytes??
