Inter thread communication is done using wait and notify (or notify all). These methods are defined in 'Object' class.

RE: Inter Thread Communication

There are three ways in which Threads communicate with each other :

wait: It tells the calling thread to give up the monitor until some other thread enters the same monitor an calls Notify or Notifyall...

notify: It wakes up the first thread that called Wait() on the same object...

NotifyAll: It allows all the threads that called Wait() on the same object.The thread having the highest priority will run first...

RE: Inter Thread Communication

Two or more threads are communication via wait() notify() and notifyAll() method of an Object class.

wait(): method will lock the monitor of the thread to not process.

notify(): method will wake the thead which undergoes waiting state the wait state is waiting to called by notify or notifyAll()

notifyAll(): method will wake the theads which undergoes waiting state.

Inter Thread Communication

Three methods are used. They are

1. wait() - makes one thread wait for some time till another thread is being executed
2. notify() - makes one wait process into ready state process
3. notifyall() - makes all the waiting processes into ready state processes
