Java Signature

Java方法的Signature是由方法的参数和返回值的类型共同构成的，下面是他们的结构︰
"(argument-types)return-type"
其中Java程序中参数类型和其对应的值如下︰
Signature                      Java中的类型
Z                                     boolean
B                                     byte
C                                     char
S                                     short
I                                       int
J                                      long
F                                     float
D                                     double
L fully-qualified-class;      fully-qualified-class

一个Java类的方法的Signature可以通过javap命令获取︰
