I am trying out a tool jhat here to test my java memory usage. It reads in a heap dump file and prints out information as html. However, the tables shows as follows:
Class Instance Count Total Size
class [B 36585 49323821
class [Lcom.sun.mail.imap.IMAPMessage; 790 16254336
class [C 124512 12832896
class [I 23080 11923504
class [Ljava.lang.Object; 13614 6664528
class java.lang.String 108982 2179640
class java.lang.Integer 219502 878008
What are those [B [C etc classes?
