| Interface | Description | 
|---|---|
| DataInput | 
 The DataInput interface provides for reading bytes from a binary stream and reconstructing from them data in any of the Java primitive types. 
 | 
| 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. 
 | 
| Flushable | 
 
 Indicates that an output object can be flushed. 
 | 
| Serializable | 
 Here to simplify porting, won't actually work... 
 | 
| 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. 
 | 
| DataInputStream | 
 A data input stream lets an application read primitive Java data types from an underlying input stream in a machine-independent way. 
 | 
| DataOutputStream | 
 A data output stream lets an application write primitive Java data types to an output stream in a portable way. 
 | 
| 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. 
 | 
| 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. 
 | 
| StringReader | 
 A specialized  
Reader that reads characters from a String in
 a sequential manner. | 
| StringWriter | |
| Writer | 
 Abstract class for writing to character streams. 
 | 
| Exception | Description | 
|---|---|
| EOFException | 
 Signals that an end of file or end of stream has been reached unexpectedly during input. 
 | 
| InterruptedIOException | 
 Signals that an I/O operation has been interrupted. 
 | 
| IOException | 
 Signals that an I/O exception of some sort has occurred. 
 | 
| 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.
