java multithreading ... Explaining

Let's say, for example, RunnableImpl is the class that implements Runnable.
This class defines the void run() method of course, which is the method that will be invoked in a seperate thread.

To launch a new Thread of RunnableImpl:

Code:

RunnableImpl impl = new RunnableImpl(); // Simply declaring a new instance of RunnableImpl
Thread t = new Thread(impl); // The Thread class takes either a Thread child or a Runnable implementation
t.start(); // This will fire RunnableImpl.run() in a seperate thread.

Note that run(); will not be reinvoked, if you want it to live past the first invocation you must put a while() loop in to prevent the code exiting run()
