How do I transfer data from one thread to another?

If you want synchronous communication between a main thread and a processing thread, you can use a SynchronousQueue. The idea is that the main thread passes data to the processing thread by calling put() , and the processing thread calls take() . Both are blocking operations.

  3. Thread Class vs Runnable Interface.
