TimeUnit sleep() method in Java with Examples

The sleep() method of TimeUnit Class is used to performs a Thread.sleep using this time unit. This is a convenience method that sleeps time arguments into the form required by the Thread.sleep method.

Syntax:

public void sleep(long timeout)
           throws InterruptedException

Parameters: This method accepts a mandatory parameters timeout which is the minimum time to sleep. If this is less than or equal to zero, then do not sleep at all.



Return Value: This method does not return anything.

Exception: This method throws InterruptedException if interrupted while sleeping.

Below program illustrate the implementation of TimeUnit sleep() method:

            time.sleep(timeToSleep);
  
            System.out.println("Slept for "

            System.out.println("Interrupted "
                               + "while Sleeping");
        }
    }
