> When I read FsActionExecutor.java, I found a not good code in this class.
> When judging which logic to use based on commands, should use "switch/case"
> replace "if/else":
> # “if/else” make the code hard to read
> # “if/else” make the code hard to extend
> # “if/else” has low efficience
> So I suggest using “switch/case” instead.
