public interface Channel
extends Closeable
```
A channel is a conduit to I/O services covering such items as files, sockets, hardware devices, I/O ports or some software component.
Channels are open upon creation, and can be closed explicitly. Once a channel is closed it cannot be re-opened, and any attempts to perform I/O operations on the closed channel result in a ClosedChannelException.
Particular implementations or sub-interfaces of Channel dictate whether they are thread-safe or not.

  All Methods Instance Methods Abstract Methods
  Modifier and Type Method Description
  
  void close()
  Closes an open channel.
  
  boolean isOpen()
  Returns true if this channel is open.

- Method Detail
  - isOpen
```
boolean isOpen()
```
    Returns true if this channel is open.
  - close
```
void close()
    throws IOException
```
    Closes an open channel. If the channel is already closed then this method has no effect. If there is a problem with closing the channel then the method throws an IOException and the exception contains reasons for the failure.
    If an attempt is made to perform an operation on a closed channel then a ClosedChannelException will be thrown on that attempt.
    If multiple threads attempt to simultaneously close a channel, then only one thread will run the closure code, and others will be blocked until the first returns.
