FileReader in Java

FileReader is meant for reading streams of characters. For reading streams of raw bytes, consider using a FileInputStream.

FileReader extends InputStreamReader.

Note:

FileReader uses the default character encoding. If you want to specify a different character decoding scheme, use an InputStreamReader on a FileInputStream instead. The InputStreamReader lets you specify the character encoding scheme to use when reading the bytes in the underlying file.
