AlreadyConnectedException, CancellationException, CancelledKeyException, ClosedSelectorException, ConnectionPendingException, FormatterClosedException, IllegalBlockingModeException, InvalidMarkException, NoConnectionPendingException, NonReadableChannelException, NonWritableChannelException, NotYetBoundException, NotYetConnectedException, OverlappingFileLockException

AlreadyConnectedException	An `AlreadyConnectedException` is thrown when an attempt is made to connect a SocketChannel that is already connected.
CancellationException	Exception indicating that the result of a value-producing task, such as a `FutureTask`, cannot be retrieved because the task was cancelled.
CancelledKeyException	A `CancelledKeyException` is thrown when an invalid selection key is used.
ClosedSelectorException	A `ClosedSelectorException` is thrown when a `selector` is closed and an I/O operation is attempted.
ConnectionPendingException	A `ConnectionPendingException` is thrown when an attempt is made to connect a `SocketChannel` that has a non-blocking connection already underway.
FormatterClosedException	A `FormatterClosedException` will be thrown if the formatter has been closed.
IllegalBlockingModeException	An `IllegalBlockingModeException` is thrown when an operation that requires a specific blocking mode is invoked on a channel that is in a different blocking mode.
InvalidMarkException	An `InvalidMarkException` is thrown when `reset()` is called on a buffer, but no mark has been set previously.
NoConnectionPendingException	A `NoConnectionPendingException` is thrown if `SocketChannel`'s `finishConnect` method is called before the `SocketChannel`'s `connect(java.net.SocketAddress)` connect} method completed without error.
NonReadableChannelException	A `NonReadableChannelException` is thrown when attempting to read from a channel that is not open for reading.
NonWritableChannelException	A `NonWritableChannelException` is thrown when attempting to write to a channel that is not open for writing.
NotYetBoundException	A `NotYetBoundException` is thrown if the server socket channel is not bound before an I/O operation is made.
NotYetConnectedException	A `NotYetConnectedException` is thrown if the socket channel is not connected before an I/O operation is invoked.
OverlappingFileLockException	An `OverlappingFileLockException` is thrown when attempting to acquire a lock that overlaps an existing or pending lock held by this process.

Inherited Methods

From class java.lang.Throwable

Throwable	fillInStackTrace() Records the stack trace from the point where this method has been called to this `Throwable`.
Throwable	getCause() Returns the cause of this `Throwable`, or `null` if there is no cause.
String	getLocalizedMessage() Returns the extra information message which was provided when this `Throwable` was created.
String	getMessage() Returns the extra information message which was provided when this `Throwable` was created.
StackTraceElement[]	getStackTrace() Returns the array of stack trace elements of this `Throwable`.
Throwable	initCause(Throwable throwable) Initializes the cause of this `Throwable`.
void	printStackTrace(PrintWriter err) Writes a printable representation of this `Throwable`'s stack trace to the specified print writer.
void	printStackTrace(PrintStream err) Writes a printable representation of this `Throwable`'s stack trace to the specified print stream.
void	printStackTrace() Writes a printable representation of this `Throwable`'s stack trace to the `System.err` stream.
void	setStackTrace(StackTraceElement[] trace) Sets the array of stack trace elements.
String	toString() Returns a string containing a concise, human-readable description of this object.

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
