An index() method is almost the same as the find() method, the only difference is that find() method returns -1 if that value is not found.
它(将)不用于方法形式、构造函数形式、方法返回类型、字段、捕获形式,或任何其他类型的变量声明。
It[will] not be available for method formals, constructor formals, method return types, fields, catch formals, or any other kind of variable declaration.
函数、方法返回接口的引用(通过返回值或者"out"参数),应当在返回前增加被返回的对象的引用计数。
Functions and methods that return interface references(via return value or via"out" parameter) shall increment the reference count of the returned object before returning..
