What will be the output of the program?

1. Deadlock will not occur if wait()/notify() is used
2. A thread will resume execution as soon as its sleep duration expires.
3. Synchronization can prevent two objects from being accessed by the same thread.
4. The wait() method is overloaded to accept a duration.
5. The notify() method is overloaded to accept a duration.
6. Both wait() and notify() must be called from a synchronized context.

Runnable target = new MyRunnable();
Thread myThread = new Thread(target);
