public Class FileReader

extends InputStreamReader
Class Inheritance

Reads text from character files using a default buffer size. Decoding from bytes to characters uses either a specified charset or the default charset.

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