JVM规范的Section 4.3.2:
Character Type Interpretation ------------------------------------------ B byte signed byte C char Unicode character D double double-precision floating-point value F float single-precision floating-point value I int integer J long long integer L<classname>; reference an instance of class S short signed short Z boolean true or false [ reference one array dimension
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String
和boolean
并返回void
。
+ V代表虚空 – dzieciou
