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.

Exception Summary

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CancelledKeyException	Unchecked exception thrown when an attempt is made to use a selection key that is no longer valid.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.
