| Package | Description | 
|---|---|
| java.nio.channels | Defines channels, which represent connections to entities that are capable of
 performing I/O operations, such as files and sockets; defines selectors, for
 multiplexed, non-blocking I/O operations. | 
| Modifier and Type | Interface and Description | 
|---|---|
| interface  | ByteChannelA channel that can read and write bytes. | 
| interface  | GatheringByteChannelA channel that can write bytes from a sequence of buffers. | 
| interface  | SeekableByteChannelA byte channel that maintains a current position and allows the
 position to be changed. | 
| Modifier and Type | Class and Description | 
|---|---|
| class  | DatagramChannelA selectable channel for datagram-oriented sockets. | 
| class  | FileChannelA channel for reading, writing, mapping, and manipulating a file. | 
| static class  | Pipe.SinkChannelA channel representing the writable end of a  Pipe. | 
| class  | SocketChannelA selectable channel for stream-oriented connecting sockets. | 
| Modifier and Type | Method and Description | 
|---|---|
| static WritableByteChannel | Channels. newChannel(OutputStream out)Constructs a channel that writes bytes to the given stream. | 
| Modifier and Type | Method and Description | 
|---|---|
| static OutputStream | Channels. newOutputStream(WritableByteChannel ch)Constructs a stream that writes bytes to the given channel. | 
| static Writer | Channels. newWriter(WritableByteChannel ch,
         CharsetEncoder enc,
         int minBufferCap)Constructs a writer that encodes characters using the given encoder and
 writes the resulting bytes to the given channel. | 
| static Writer | Channels. newWriter(WritableByteChannel ch,
         String csName)Constructs a writer that encodes characters according to the named
 charset and writes the resulting bytes to the given channel. | 
| abstract long | FileChannel. transferTo(long position,
          long count,
          WritableByteChannel target)Transfers bytes from this channel's file to the given writable byte
 channel. |
