There are two ways to do Async in Java, since Java 7 : NIO and AIO. Both are asynchronous IO. The difference between NIO and AIO is that when you try to read or write something, this can be done in a simpler way, as you may pass the reference to an handler which will be called automatically, when you have to take care of this with NIO. To be clear, the distinction should be between blocking IO and non-blocking IO. NIO and AIO are part of the non-blocking IO. -- Regards, Cordialement, Emmanuel Lécharny www.iktek.com
