java.lang.Class

20.3

If this class object represents a class of arrays, then the name consists of the

name of the element type in Java signature format, preceded by one or more  

[

characters representing the depth of array nesting. For example:

(new Object[3]).getClass().getName()

returns

"[Ljava.lang.Object;"

 and:

(new int[3][4][5][6][7][8][9]).getClass().getName()

returns

"[[[[[[[I"

. The encoding of element type names is as follows:

B

byte

C

char

D

double

F

float

I

int

J

long

Lclassname; class or interface

S

short

Z

boolean

A class or interface name

classname

the example above. For a full description of type descriptors see the chapter on the

format of class files in the
