推荐答案

为什么需要一个FileInputStream具体一点吗？一般情况下，你不必关心的InputStream的底层实现，你只是从它读。也许的您的实施应该是不可知的InputStream

Why do you need a FileInputStream specifically? In general, you don't have to care about the underlying implementation of the InputStream, you just read from it. Maybe your implementation should be InputStream agnostic.
