Java Tutorial/Thread/Sleep Pause

Add a delay

public class Main {
  public static void main(String[] args) {
    for (int i = 0; i < 10; i++) {
      System.out.println("i = " + i);
      try {
        Thread.sleep(1000);
      } catch (InterruptedException ie) {
        ie.printStackTrace();
      }
    }
  }
}

Pause the execution

class Wait {
  public static void oneSec() {
    try {
      Thread.currentThread().sleep(1000);
    } catch (InterruptedException e) {
      e.printStackTrace();
    }
  }
  public static void manySec(long s) {
    try {
      Thread.currentThread().sleep(s * 1000);
    } catch (InterruptedException e) {
      e.printStackTrace();
    }
  }
}
public class Main{
  public static void main(String args[]) {
    Wait.oneSec();
    Wait.manySec(5);
  }
}

Pause the execution of a thread using sleep()

class Wait {
  public static void bySeconds(long s) {
    try {
      Thread.currentThread().sleep(s * 1000);
    } catch (InterruptedException e) {
      e.printStackTrace();
    }
  }
}
public class Main {
  public static void main(String args[]) {
    System.out.println("Wait");
    Wait.bySeconds(5);
    System.out.println("Done");
  }
}

Pausing the Current Thread: a thread can temporarily stop execution.

public class Main {
  public static void main(String[] argv) throws Exception {
    long numMillisecondsToSleep = 5000; 
    Thread.sleep(numMillisecondsToSleep);
  }
}
