Summary

Threads can communicate and signal each other by several mechanisms in Java. The wait/notify mechanism ( wait() , notify() , and notifyAll() ) provides a multithread-safe way for one thread to signal another that a value has changed. I showed you that it is important to make sure to avoid missed notifications and early notifications.

In addition, threads can use the join() method of Thread to wait for other threads to die. A thread can also stream data through a pipe to another thread using the classes PipedInputStream , PipedOutputStream , PipedReader , and PipedWriter .

Threads can also use thread-specific variables that keep a different value for different threads by using the classes ThreadLocal and InheritableThreadLocal .
