public static InputStream newInputStream(ReadableByteChannel ch)
 The read methods of the resulting stream will throw an
 IllegalBlockingModeException if invoked while the underlying
 channel is in non-blocking mode.  The stream will not be buffered, and
 it will not support the mark or reset methods.  The stream will be safe for access by
 multiple concurrent threads.  Closing the stream will in turn cause the
 channel to be closed.  
ch - The channel from which bytes will be readpublic static OutputStream newOutputStream(WritableByteChannel ch)
 The write methods of the resulting stream will throw an
 IllegalBlockingModeException if invoked while the underlying
 channel is in non-blocking mode.  The stream will not be buffered.  The
 stream will be safe for access by multiple concurrent threads.  Closing
 the stream will in turn cause the channel to be closed.  
ch - The channel to which bytes will be writtenpublic static InputStream newInputStream(AsynchronousByteChannel ch)
 The stream will not be buffered, and it will not support the mark or reset methods.  The
 stream will be safe for access by multiple concurrent threads.  Closing
 the stream will in turn cause the channel to be closed.  
ch - The channel from which bytes will be readpublic static OutputStream newOutputStream(AsynchronousByteChannel ch)
The stream will not be buffered. The stream will be safe for access by multiple concurrent threads. Closing the stream will in turn cause the channel to be closed.
ch - The channel to which bytes will be writtenpublic static ReadableByteChannel newChannel(InputStream in)
The resulting channel will not be buffered; it will simply redirect its I/O operations to the given stream. Closing the channel will in turn cause the stream to be closed.
in - The stream from which bytes are to be readpublic static WritableByteChannel newChannel(OutputStream out)
The resulting channel will not be buffered; it will simply redirect its I/O operations to the given stream. Closing the channel will in turn cause the stream to be closed.
out - The stream to which bytes are to be writtenpublic static Reader newReader(ReadableByteChannel ch, CharsetDecoder dec, int minBufferCap)
 The resulting stream will contain an internal input buffer of at
 least minBufferCap bytes.  The stream's read methods
 will, as needed, fill the buffer by reading bytes from the underlying
 channel; if the channel is in non-blocking mode when bytes are to be
 read then an IllegalBlockingModeException will be thrown.  The
 resulting stream will not otherwise be buffered, and it will not support
 the mark or reset methods.
 Closing the stream will in turn cause the channel to be closed.  
ch - The channel from which bytes will be readdec - The charset decoder to be usedminBufferCap - The minimum capacity of the internal byte buffer,

 The resulting stream will contain an internal output buffer of at
 least minBufferCap bytes.  The stream's write methods
 will, as needed, flush the buffer by writing bytes to the underlying
 channel; if the channel is in non-blocking mode when bytes are to be
 written then an IllegalBlockingModeException will be thrown.
 The resulting stream will not otherwise be buffered.  Closing the stream
 will in turn cause the channel to be closed.
