Is there is a way to see how many bytes an object instance takes up in the memory?



E.g.


String[] myStringArray = {"1", "2", "3"};


To my knowledge the instance myStringArray would take up 3 x 16 bytes = 48 bytes since Java uses Unicode were each character is represented by 16 bytes.



But is there any way to retrieve this byte count through a method call? What if the object contains references to other objects? Can there memory usage be calculated as well?
