The sleep method in threading

The Thread class is having a sleep(long interval) . It makes to sleep the current thread for the specified interval.The interval specified will be minimum time it stays in the sleeping state.We cannot guarantee , when it is returning to running .This method is throwing InterruptedException .So in code we need to handle that also

The sleep method in threading  – Example

Let us see an example . Here we are trying to display numbers from 1 to 10 with an interval of 5 seconds.After printing each number , thread stays in sleeping mode for 5000 ms.

public class SleepSample extends Thread {
public SleepSample() {
}
public void run() {
int number = 0;
while (number < 10) { System.out.println("Number = " + number); try { number++; sleep(5000); } catch (InterruptedException e) { e.printStackTrace(); } } } public static void main(String[] args) { SleepSample sample = new SleepSample(); sample.start(); } }

The program just prints the numbers with good interval.It is enough to understand the concept.
