java - both File.isFile() and File.isDirectory() is returning false

Question

I have a file with name "aaa?aa.xls"

For this, File.isFile() and File.isDirectory() is returning false? why it is returning false in Linux?

Answer 1

Please try the following code example

if(!pFile.exists()){
   throw new FileNotFoundException();
}

boolean isDir = pFile.isDirectory();

boolean isFile = pfile.isFile();

the file is not a file

if it is not a directory and, in addition, satisfies other system-dependent criteria

if the exception is thrown, you have to check the file path.
