Question: What are the differences between the methods sleep() and wait()?

• The code sleep(1000); puts thread aside for exactly one second. The code wait(1000), causes a wait of up to one second. A thread could stop waiting earlier if it receives the notify() or notifyAll() call. 
  
• The method wait() is defined in the class Object and the method sleep() is defined in the class Thread.
