What is technical difference if I pass Runnable in two different way. Please explain..

Thread thread = new Thread (new RunnableClass());

or

RunnableClass runnable = new RunnableClass();
Thread thread = new Thread(runnable);

Thanks in Advance...

The difference is that you'll have another reference variable poiinting to the RunnableClass instance. Nothing else.

Hi Rajiv,

As mentioned by Sebastian, the difference is that you would have reference of runnable object in the second case. The second syntax is preferred when we want to create multiple threads on the same runnable instance.
