| 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. | 
| java.util | Contains the collections framework, legacy collection classes, event model,
date and time facilities, internationalization, and miscellaneous utility
classes (a string tokenizer, a random-number generator, and a bit array). | 
| Modifier and Type | Interface and Description | 
|---|---|
| interface  | ByteChannelA channel that can read and write bytes. | 
| interface  | ScatteringByteChannelA channel that can read bytes into 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.SourceChannelA channel representing the readable end of a  Pipe. | 
| class  | SocketChannelA selectable channel for stream-oriented connecting sockets. | 
| Modifier and Type | Method and Description | 
|---|---|
| static ReadableByteChannel | Channels. newChannel(InputStream in)Constructs a channel that reads bytes from the given stream. | 
| Modifier and Type | Method and Description | 
|---|---|
| static InputStream | Channels. newInputStream(ReadableByteChannel ch)Constructs a stream that reads bytes from the given channel. | 
| static Reader | Channels. newReader(ReadableByteChannel ch,
         CharsetDecoder dec,
         int minBufferCap)Constructs a reader that decodes bytes from the given channel using the
 given decoder. | 
| static Reader | Channels. newReader(ReadableByteChannel ch,
         String csName)Constructs a reader that decodes bytes from the given channel according
 to the named charset. | 
| abstract long | FileChannel. transferFrom(ReadableByteChannel src,
            long position,
            long count)Transfers bytes into this channel's file from the given readable byte
 channel. | 
| Constructor and Description | 
|---|
| Scanner(ReadableByteChannel source)Constructs a new  Scannerthat produces values scanned
 from the specified channel. | 
| Scanner(ReadableByteChannel source,
       String charsetName)Constructs a new  Scannerthat produces values scanned
 from the specified channel. |
