Asynchronous IO in Java?

Also does java.nio use threads in the backround (as I think .NET’s async-socket-library does, maybe it’s been changed) or is it “true” async io using a proper select call? Answer Java’s NIO package (as of Java6), provides support for non-blocking I/O only, via Selectors. Java7 is hopefully
