FileInputStream encoding for ANCI?

Question

Java

There is a method that implements the BufferedReader construction filePathReader = new BufferedReader(new InputStreamReader(new FileInputStream(reader.readLine()))
The program must read a text file and output its contents to the console, the construction described above takes FileInputStream(reader.readLine()) as parameters )), reader.readline() - the path to the text file
Next, through the loop, I display the contents of the file to the console character-by-character
The problem is that the program does not read Cyrillic, displays a question mark instead of letters
Latin outputs norms
If you save a text file with utf8 encoding, then everything is OK
But how to read exactly for ansi

Answer 1

You need to read the file in the encoding in which it is saved. If the encoding is not set explicitly, the system encoding is used.
