Classes in java.io used by java.io
BufferedReader
          Read text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines.
DataInput
          The DataInput interface provides for reading bytes from a binary stream and reconstructing from them data in any of the Java primitive types.

          The DataOutput interface provides for converting data from any of the Java primitive types to a series of bytes and writing these bytes to a binary stream.
File
          An abstract representation of file and directory pathnames.

FilterOutputStream
          This class is the superclass of all classes that filter output streams.
FilterReader
          Abstract class for reading filtered character streams.
InputStream
          This abstract class is the superclass of all classes representing an input stream of bytes.
