Quick Answer
Producer-consumer: producer puts items in a shared buffer, consumer takes them. Without coordination: producer overwhelms buffer (full) or consumer reads empty buffer. Solution: BlockingQueue - put() blocks if full, take() blocks if empty, no explicit wait/notify needed. ArrayBlockingQueue (bounded, prevents OOM) or LinkedBlockingQueue (unbounded). Much simpler than manual wait/notify.
Answer
Producer adds data; consumer removes it. Requires thread coordination and shared buffers. Uses wait(), notify(), or BlockingQueue.
