- Class
  Description
  ByteArrayInputStream
  A ByteArrayInputStream contains an internal buffer that contains bytes that may be read from the stream.
  ByteArrayOutputStream
  This class implements an output stream in which the data is written into a byte array.
  DataInput
  The DataInput interface provides for reading bytes from a binary stream and reconstructing from them data in any of the Java primitive types.
  DataInputStream
  A data input stream lets an application read primitive Java data types from an underlying input stream in a machine-independent way.
  DataOutput
  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.
  DataOutputStream
  A data output stream lets an application write primitive Java data types to an output stream in a portable way.
  EOFException
  Signals that an end of file or end of stream has been reached unexpectedly during input.
  FileNotFoundException
  Signals that an attempt to open the file denoted by a specified pathname has failed.
  Flushable
  Indicates that an output object can be flushed.
  InputStream
  This abstract class is the superclass of all classes representing an input stream of bytes.
  InputStreamReader
  An InputStreamReader is a bridge from byte streams to character streams: It reads bytes and translates them into characters.
  InterruptedIOException
  Signals that an I/O operation has been interrupted.
  IOException
  Signals that an I/O exception of some sort has occurred.
  OutputStream
  This abstract class is the superclass of all classes representing an output stream of bytes.
  OutputStreamWriter
  An OutputStreamWriter is a bridge from character streams to byte streams: Characters written to it are translated into bytes.
  PrintStream
  A PrintStream adds functionality to another output stream, namely the ability to print representations of various data values conveniently.
  Reader
  Abstract class for reading character streams.
  Serializable
  Here to simplify porting, won't actually work...
  StringReader
  A specialized `Reader` that reads characters from a `String` in a sequential manner.
  StringWriter
  UnsupportedEncodingException
  The Character Encoding is not supported.
  UTFDataFormatException
  Signals that a malformed UTF-8 string has been read in a data input stream or by any class that implements the data input interface.
  Writer
  Abstract class for writing to character streams.
