Java NonReadableChannelException is an exception thrown when an attempt is made to read from a Java channel that does not support reading. This can occur when trying to read from a Java FileChannel or other java.nio channels that are not open for reading. Introduced in Java 2007 with Java 7, NonReadableChannelException is part of Java's java.nio.channels package and ensures that only valid operations are performed on channels.
