Java.io.FileNotFoundException exception, one is "Access Denied", and the second is "the system cannot find the specified path"

About Java.io.FileNotFoundException Exceptions

Because this exception throws two things: one is "Access Denied", and the other is "the system cannot find the specified path"

This only tells you when to leave the denied access, when the specified path is not found.

The reason for this is that when you construct a file object, you can specify the path to the files, and even if they do not exist, you can construct the document object.

But now you're going to do input and output operations on the files, that is, InputStream and outputstream operations,

If the completed path does not exist, the system cannot find the specified path , and if a directory is specified, an Access denied exception is reported .
