Interfaces

ByteChannel A channel that can read and write bytes. 
Channel A nexus for I/O operations. 
GatheringByteChannel A channel that can write bytes from a sequence of buffers. 
InterruptibleChannel A channel that can be asynchronously closed and interrupted. 
NetworkChannel A channel to a network socket. 
ReadableByteChannel A channel that can read bytes. 
ScatteringByteChannel A channel that can read bytes into a sequence of buffers. 
SeekableByteChannel A byte channel that maintains a current position and allows the position to be changed. 
WritableByteChannel A channel that can write bytes. 

Classes

Channels Utility methods for channels and streams. 
DatagramChannel A selectable channel for datagram-oriented sockets. 
FileChannel A channel for reading, writing, mapping, and manipulating a file. 
FileChannel.MapMode A typesafe enumeration for file-mapping modes. 
FileLock A token representing a lock on a region of a file. 
Pipe A pair of channels that implements a unidirectional pipe. 
Pipe.SinkChannel A channel representing the writable end of a Pipe
Pipe.SourceChannel A channel representing the readable end of a Pipe
SelectableChannel A channel that can be multiplexed via a Selector
SelectionKey A token representing the registration of a SelectableChannel with a Selector
Selector A multiplexor of SelectableChannel objects. 
ServerSocketChannel A selectable channel for stream-oriented listening sockets. 
SocketChannel A selectable channel for stream-oriented connecting sockets. 

Exceptions

AlreadyBoundException Unchecked exception thrown when an attempt is made to bind the socket a network oriented channel that is already bound. 
AlreadyConnectedException Unchecked exception thrown when an attempt is made to connect a SocketChannel that is already connected. 
AsynchronousCloseException Checked exception received by a thread when another thread closes the channel or the part of the channel upon which it is blocked in an I/O operation. 
CancelledKeyException Unchecked exception thrown when an attempt is made to use a selection key that is no longer valid. 
ClosedByInterruptException Checked exception received by a thread when another thread interrupts it while it is blocked in an I/O operation upon a channel. 
ClosedChannelException Checked exception thrown when an attempt is made to invoke or complete an I/O operation upon channel that is closed, or at least closed to that operation. 
ClosedSelectorException Unchecked exception thrown when an attempt is made to invoke an I/O operation upon a closed selector. 
ConnectionPendingException Unchecked exception thrown when an attempt is made to connect a SocketChannel for which a non-blocking connection operation is already in progress. 
FileLockInterruptionException Checked exception received by a thread when another thread interrupts it while it is waiting to acquire a file lock. 
IllegalBlockingModeException Unchecked exception thrown when a blocking-mode-specific operation is invoked upon a channel in the incorrect blocking mode. 
IllegalSelectorException Unchecked exception thrown when an attempt is made to register a channel with a selector that was not created by the provider that created the channel. 
NoConnectionPendingException Unchecked exception thrown when the finishConnect method of a SocketChannel is invoked without first successfully invoking its connect method. 
NonReadableChannelException Unchecked exception thrown when an attempt is made to read from a channel that was not originally opened for reading. 
NonWritableChannelException Unchecked exception thrown when an attempt is made to write to a channel that was not originally opened for writing. 
NotYetBoundException Unchecked exception thrown when an attempt is made to invoke an I/O operation upon a server socket channel that is not yet bound. 
NotYetConnectedException Unchecked exception thrown when an attempt is made to invoke an I/O operation upon a socket channel that is not yet connected. 
OverlappingFileLockException Unchecked exception thrown when an attempt is made to acquire a lock on a region of a file that overlaps a region already locked by the same Java virtual machine, or when another thread is already waiting to lock an overlapping region of the same file. 
UnresolvedAddressException Unchecked exception thrown when an attempt is made to invoke a network operation upon an unresolved socket address. 
UnsupportedAddressTypeException Unchecked exception thrown when an attempt is made to bind or connect to a socket address of a type that is not supported.
