1. Class的名字
^^^^^^^^^^^^^^
...............................................................................
public String getName()

Returns the name of the entity (class, interface, array class, 
primitive type, or void) represented by this Class object, as a String. 
If this class object represents a reference type that is not an array 
type then the binary name of the class is returned, as specified by the 
Java Language Specification, Second Edition. 

If this class object represents a primitive type or void, then the name 
returned is a String equal to the Java language keyword corresponding 
to the primitive type or void. 

If this class object represents a class of arrays, then the internal 
form of the name consists of the name of the element type preceded by 
one or more '[' characters representing the depth of the array nesting. 
The encoding of element type names is as follows: 

Element Type                Encoding  
boolean                     Z  
byte                        B  
char                        C  
class or interface          Lclassname;  
double                      D  
float                       F  
int                         I  
long                        J  
short                       S  

The class or interface name classname is the binary name of the class 
specified above. 

Examples: 

 String.class.getName()
     returns "java.lang.String"
 byte.class.getName()
     returns "byte"
 (new Object[3]).getClass().getName()
     returns "[Ljava.lang.Object;"
 (new int[3][4][5][6][7][8][9]).getClass().getName()
     returns "[[[[[[[I"
................................................................................
简单来讲：
    1)  [   表示数组，有几个就是几维。
    2)  L;  与[结合，表示类的数组，类型就是L和;中间所夹的类型。
    3)  对于非数组类型的，直接返回它的名字。

2. 对像的Class
^^^^^^^^^^^^^^
..................................................

__.class 或 __.TYPE

boolean    ->     boolean.class   =    Boolean.TYPE
byte       ->     byte.class      =    Byte.TYPE
char       ->     char.class      =    Character.TYPE
int        ->     int.class       =    Integer.TYPE
short      ->     short.class     =    Short.TYPE
long       ->     long.class      =    Long.TYPE
float      ->     float.class     =    Float.TYPE
double     ->     double.class    =    Double.TYPE
void       ->     void.class      =    Void.TYPE

int[]      ->     int[].class
short[][]  ->     short[][].class
String[]   ->     String[].class

(可能还有其他的表示方法，但目前我还不会)
