Both wait() and sleep() methods play an important role in Java programming. Both methods look the same, but there is some difference in their working and existence within a program.
Let's see how they differ from each other:
|wait method is one of the methods of java.lang.Object class.||sleep method is one of the methods of java.lang.Thread class.|
|Only a synchronized block or method can call the wait() method.||From any point or context in a program, you can call the sleep() method.|
|notify() and notifyAll() methods are used for waking the waiting thread.||Interrupts are used for waking the sleeping thread.|
|This method is usually implemented in a Java program for performing multi-thread-synchronization.||This method is generally applied for controlling the time of execution for a single thread.|
