    Identifying class in output of jmap -histo

    843798
      I ran jmap -histo on a process I was running to find out the contents of the heap and get this output:
      $ jmap -histo 2188
      
       num     #instances         #bytes  class name
      ----------------------------------------------
         1:        149861       68712760  [D
         2:         13872        7537936  [I
         3:         47407        5122416  <constMethodKlass>
         4:         47407        3799968  <methodKlass>
      What are the first two entries? I'm guessing Double[] and Integer[], but can anyone confirm this for me?
