J    long   long integer 
L<classname>; reference  an instance of class 
S    short   signed short

这些类型签名原语:

Type Signature Java Type V void Z boolean B byte C char S short I int J long F float D double L fully-qualified-class ; fully-qualified-class [ type type[]

setFeature需要Stringboolean并返回void
