Oh okay. &nbsp; But if I want ot make a network connection in the real-time environment, wouldn't it be critical spawning multiple threads and not having asynchronous i/o? &nbsp; Also all the sample codes I've seen uses this feature and mine doesn't so I was wondering if I was doing something very inefficient...

Well, i'm not sure what you're doing (you didn't mention that above), so i can't really answer that...

asynchronous i/o

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
