Examples of java.nio.channels.ClosedChannelException

java.nio.channels.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. That this exception is thrown does not necessarily imply that the channel is completely closed. A socket channel whose write half has been shut down, for example, may still be open for reading. @version 1.9, 01/11/19 @since 1.4
