Scanner with just a File VS Scanner with FileReader and File

Guys i'm just wandering what is the difference between these lines

  1. Scanner file = new Scanner(new FileReader(new File(filePath)));
  2. Scanner file = new Scanner(new File(filePath));
  3. Scanner file = new Scanner(new FileReader(filePath));

is their any kind of instance when you will use them? or their all the same?

They're all identical. The File constructors are for convenience. Sometimes you will get other Readers (not from a File) or need to construct the FileReader yourself (in order to specify an encoding) in which case the Reader constructor is important.
