Java 1.4

This class defines static methods that provide a bridge between the byte stream and character stream classes of the java.io package and the channel classes of java.nio.channels . Channels is never intended to be instantiated : it serves solely as a placeholder for static methods. These methods create byte channels based on java.io byte streams, and create java.io byte streams based on byte channels. Note that the channel objects returned by the newChannel( ) methods may not implement InterruptibleChannel , and so may not be asynchonously closeable and interruptible like other channel classes in this package. Channels also defines methods to create character streams ( java.io.Reader and java.io.Writer ) based on the combination of a byte channel and a character encoding. The encoding may be specified by charset name , or with a CharsetDecoder or CharsetEncoder (see java.nio.charset ).
