Pause Execution with Sleep In Java Example

Chapter: Thread Last Updated: 21-07-2016 10:45:37 UTC

Program:

            /* ............... START ............... */
                
import java.util.*;
import java.text.*;

public class JavaSleepPauseExecution {
	public static void main(String[] args) throws InterruptedException {

		Calendar cal;
		DateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");

		cal = Calendar.getInstance();
		System.out.println(dateFormat.format(cal.getTime()));

		Thread.sleep(5000);

		cal = Calendar.getInstance();
		System.out.println(dateFormat.format(cal.getTime()));
	}
}
                /* ............... END ............... */
        

Output

18:11:49
18:11:54

Notes:

  • Thread.sleep() causes the current thread to suspend execution for a specified period.
  • Thread.sleep() sends the current thread into the “Not Runnable” state for some amount of time. The thread keeps the monitors it has acquired - i.e. if the thread is currently in a synchronized block or method no other thread can enter this block or method.
